Sceaduinar

This gargoyle-like creature has long spiky legs and a bat-like head—its body seems to be made of living, dark purple crystal.

Sceaduinars are strange creatures born of pure entropy, the antithesis of creation and life. In the cold heart of the Negative Energy Plane, the un-substance of that realm coalesces into snowflake-like crystals, and it is from these strange formations that sceaduinars arise, breaking free from their jagged “eggs” fully grown. They hate the living and the undead with equal passion, perhaps out of jealousy for those who have a spark of life (even if that spark is provided by a corruption of life in the form of undeath), though they usually ignore creatures from the Outer Sphere. They believe their positive energy counterparts, the jyoti, long ago stole their ability to create, breaking the parallel between the two energy planes and forcing these void-dwellers into an unwanted role of pure destruction. In a way, their hatred parallels that of another native of the Negative Energy Plane—the nightshade. Yet despite their similar goals, the sceaduinars see nightshades as just another corruption of life worthy of destruction— even though very few sceaduinars are powerful enough to directly oppose one of these deadly undead. Sceaduinars are quite intelligent, yet they have no real society to speak of. When they gather together, it is always to form a larger band to strike against a particularly dangerous foe.

 NE Medium outsider (extraplanar)

     The Extraplanar subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

     An Outsider is at least partially composed of the essence (but not necessarily the material) of some plane other than the Material Plane. Some creatures start out as some other type and become outsiders when they attain a higher (or lower) state of spiritual existence. An outsider has the following traits:
   • Unlike most living creatures, an outsider does not have a dual nature—its soul and body form one unit. When an outsider is slain, no soul is set loose. Spells that restore souls to their bodies, such as raise dead, reincarnate, and resurrection, don’t work on an outsider. It takes a different magical effect, such as limited wish, wish, miracle, or true resurrection to restore it to life.
   • Proficient with all simple and martial weapons and any weapons mentioned in its entry.
   • Proficient with whatever type of armor (light, medium, or heavy) it is described as wearing, as well as all lighter types. Outsiders not indicated as wearing armor are not proficient with armor. Outsiders are proficient with shields if they are proficient with any form of armor.
   • Outsiders breathe, but do not need to eat or sleep (although they can do so if they wish).

 Init +5; Senses darkvision 120 ft., lifesense, low-light vision; Perception +17

 Lifesense (Ex) Using nonvisual senses, this monster notices and locates living creatures within 60 feet. Invisibility, darkness, and most kinds of concealment are irrelevant, though the monster must have line of effect to a living creature to discern that creature. The monster usually does not need to make Perception checks to notice creatures within range of its lifesense ability.

     Darkvision is the extraordinary ability to see with no light source at all, out to a range specified. Darkvision is black-and-white only (colors cannot be discerned). It does not allow creatures to see anything that they could not see otherwise—invisible objects are still invisible, and illusions are still visible as what they seem to be. Likewise, darkvision subjects a creature to gaze attacks normally. The presence of light does not spoil darkvision.

     A creature with low-light vision can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of dim light. It retains the ability to distinguish color and detail under these conditions.

 Negative Energy Affinity (Ex) This creature is alive but is healed by negative energy and harmed by positive energy, as if it were an undead creature.

     A creature with DR ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below. 
     The entry indicates the amount of damage ignored and the type of weapon that negates the ability. 
     Some monsters are vulnerable to piercing, bludgeoning, or slashing damage. Others are vulnerable to certain materials, such as adamantine, alchemical silver, or cold-forged iron. Attacks from weapons that are not of the correct type or made of the correct material have their damage reduced, although a high enhancement bonus can overcome some forms of damage reduction. 
     Some monsters are vulnerable to magic weapons. Any weapon with at least a +1 magical enhancement bonus on attack and damage rolls overcomes the damage reduction of these monsters. Such creatures’ natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction. 
     A few very powerful monsters are vulnerable only to epic weapons—that is, magic weapons with at least a +6 enhancement bonus. Such creatures’ natural weapons are also treated as epic weapons for the purpose of overcoming damage reduction. 
     Some monsters are vulnerable to good-, evil-, chaotically, or lawfully aligned weapons. When a cleric or inquisitor casts align weapon, affected weapons might gain one or more of these properties, and certain magic weapons have these properties as well. A creature with an alignment subtype (chaotic, evil, good, or lawful) can overcome this type of damage reduction with its natural weapons and weapons it wields as if the weapons or natural weapons had an alignment (or alignments) that matched the subtype(s) of the creature. 
     When a damage reduction entry has a — after the slash, no weapon negates the damage reduction. 
     A few creatures are harmed by more than one kind of weapon. A weapon that inflicts damage of either type overcomes this damage reduction. 
     A few other creatures require combinations of different types of attacks to overcome their damage reduction, and a weapon must be both types to overcome this type of damage reduction. A weapon that is only one type is still subject to damage reduction.

     A creature with immunities takes no damage from listed sources. Immunities can also apply to afflictions, conditions, spells (based on school, level, or save type), and other effects. A creature that is immune does not suffer from these effects, or any secondary effects that are triggered due to an immune effect.

     A creature with resistance to energy ignores some damage of a certain type per attack, but it does not have total immunity. Each resistance ability is defined by what energy type it resists and how many points of damage are resisted. It doesn’t matter whether the damage has a mundane or magical source. When resistance completely negates the damage from an energy attack, the attack does not disrupt spellcasting. This resistance does not stack with the resistance that a spell might provide.

     A creature with Spell Resistance has the extraordinary ability to avoid the effects of spells and spell-like abilities that directly affect it. To determine if a spell or spell-like ability works against a creature with spell resistance, the caster must make a caster level check (1d20 + caster level). If the result equals or exceeds the creature’s spell resistance, the spell works normally, although the creature is still allowed a saving throw.

 OFFENSE

 Speed 40 ft., fly 90 ft. (good)

     A creature with a Fly speed can cease or resume flight as a free action on their turn. Without making a check, a flying creature can remain flying at the end of its turn so long as it moves a distance greater than half its speed. It can also turn up to 45 degrees during its turn by sacrificing 5 feet of movement, can rise at half speed at an angle of 45 degrees (ignoring the penalty for diagonal movement), and can descend at any angle at normal speed. At the beginning of their turn a flying creature can move in a different direction than they did previously without needing a Fly check.
     A creature with a natural fly speed receives a bonus (or penalty) on Fly skill checks depending on its maneuverability:
 • Clumsy –8
 • Poor –4
 • Average +0
 • Good +4
 • Perfect +8
     Creatures without a maneuverability rating are assumed to have average maneuverability and take no penalty on Fly checks. These modifiers are already included in the creature’s statblock.

 Melee bite +14 (1d6+3 plus 1d6 negative energy and energy drain), 2 wings +9 (1d6+1 plus 1d6 negative energy)

 Special Attacks energy drain (1 level, DC 17), entropic touch

     Energy Drain supernaturally saps a living opponent’s vital energy and happens automatically when a melee or ranged attack hits. Each successful energy drain bestows one or more negative levels (the creature’s description specifies how many) with no saving throw. If an attack that includes an energy drain scores a critical hit, it bestows twice the listed number of negative levels. Unless otherwise specified in the creature’s description, a draining creature gains 5 temporary hit points for each negative level it bestows on an opponent. These temporary hit points last for a maximum of 1 hour. Negative levels remain until 24 hours have passed or until they are removed with a spell such as restoration. If a negative level is not removed before 24 hours have passed, the affected creature must attempt a Fortitude save (DC 10 + 1/2 the draining creature’s racial HD + the draining creature’s Cha modifier; the exact DC is given in the creature’s descriptive text). On a success, the negative level goes away with no harm to the creature. On a failure, the negative level becomes permanent. A separate saving throw is required for each negative level. 

 Spell-Like Abilities (CL 9th; concentration +12)

     Spell-like abilities are magical and work just like spells (though they are not spells and so have no verbal, somatic, focus, or material components). They go away in an antimagic field and are subject to spell resistance if the spell the ability is based on would be subject to spell resistance.
     A spell-like ability usually has a limit on how often it can be used. A constant spell-like ability or one that can be used at will has no use limit; unless otherwise stated, a creature can only use a constant spell-like ability on itself. Reactivating a constant spell-like ability is a swift action. Using all other spell-like abilities is a standard action unless noted otherwise, and doing so provokes attacks of opportunity. It is possible to make a concentration check to use a spell-like ability defensively and avoid provoking an attack of opportunity, just as when casting a spell. A spell-like ability can be disrupted just as a spell can be. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled.
     For creatures with spell-like abilities, a designated caster level defines how difficult it is to dispel their spell-like effects and to define any level-dependent variables (such as range and duration) the abilities might have. The creature’s caster level never affects which spell-like abilities the creature has; sometimes the given caster level is lower than the level a spellcasting character would need to cast the spell of the same name. If no caster level is specified, the caster level is equal to the creature’s Hit Dice. The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Charisma modifier.
     Some spell-like abilities duplicate spells that work differently when cast by characters of different classes. A monster’s spell-like abilities are presumed to be the sorcerer/wizard versions. If the spell in question is not a sorcerer/wizard spell, then default to cleric, druid, bard, paladin, and ranger, in that order.

     When performing a combat maneuver, you must use an action appropriate to the maneuver you are attempting to perform. While many combat maneuvers can be performed as part of an attack action, full-attack action, or attack of opportunity (in place of a melee attack), others require a specific action. Unless otherwise noted, performing a combat maneuver provokes an attack of opportunity from the target of the maneuver. If you are hit by the target, you take the damage normally and apply that amount as a penalty to the attack roll to perform the maneuver. If your target is immobilized, unconscious, or otherwise incapacitated, your maneuver automatically succeeds (treat as if you rolled a natural 20 on the attack roll). If your target is stunned, you receive a +4 bonus on your attack roll to perform a combat maneuver against it.
     When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target’s Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.
     If your attack roll equals or exceeds the CMD of the target, your maneuver is a success and has the listed effect. Some maneuvers, such as bull rush, have varying levels of success depending on how much your attack roll exceeds the target’s CMD. Rolling a natural 20 while attempting a combat maneuver is always a success (except when attempting to escape from bonds), while rolling a natural 1 is always a failure.

 Entropic Touch (Ex) A sceaduinar’s natural attacks can strike incorporeal creatures as if they were ghost touch weapons. All of a sceaduinar’s natural attacks deal +1d6 points of negative energy damage to the target. This energy does not heal creatures healed by inflict spells. 

 Void Child (Ex) Sceaduinars are immune to effects that target souls (such as trap the soul) or require knowledge of a creature’s identity (such as scrying). When one is slain, it cannot be restored to life by magic save by a miracle or wish, or by divine intervention.

Nightwing

This enormous, bat-like creature is shaped from utter darkness, its eyes tiny red stars in the blackest night.

The least of the known types of nightshade, the nightwing is nevertheless a deadly foe. Nightwings often serve more powerful nightshades as aerial support. These nightshades are also the most likely to be found serving a non-undead master—nightwings are often used by powerful mortals as guardians or sentinels. Despite this, nightwings still hope to someday slay any master they serve. They enter servitude primarily as a method of aiding a destructive or murderous mortal in their task of mass murder; once this task is over, or if at any point the nightwing believes its master is slacking in its murderous duties, the nightwing is swift to turn on its one-time ally. A nightwing found on the Material Plane not in the employ of a more powerful master is typically encountered in rugged terrain where there are numerous locations that can provide shelter when the sun rises. The monsters prefer caves and abandoned buildings for this purpose. A nightwing’s body is 20 feet long, but its wingspan is 80 feet. It weighs 4,500 pounds.

     Undead are once-living creatures animated by spiritual or supernatural forces. An undead creature has the following traits (unless otherwise noted in a creature’s entry).
   • No Constitution score. undead use their Charisma score in place of their Constitution score when calculating hit points, Fortitude saves, and any special ability that relies on Constitution (such as when calculating a breath weapon’s DC).
   • Cannot heal damage on its own if it has no Intelligence score, although it can be healed. Negative energy such as an inflict spell can heal undead creatures. The fast healing special quality works regardless of the creature’s Intelligence score.
   • Not affected by raise dead and reincarnate spells or abilities. Resurrection and true resurrection can affect undead creatures. These spells turn undead creatures back into the living creatures they were before becoming undead.

 Magic Drain (Su) The bite of a nightwing drains magical power and energy. When a nightwing bites a foe, the victim must make a DC 23 Will save or one spell effect currently affecting him immediately ends—determine which spell is drained randomly if the target is under the effects of more than one spell. The nightwing heals damage equal to twice the level of the spell drained—hit points in excess of its maximum are instead gained as temporary hit points that last for 1 hour. If a nightwing attempts to sunder a magic item with its bite, its magic-draining bite renders the item nonmagical for 1d4 rounds (if the item is a permanent magic item), drains 1d8 charges (if the item has charges), or renders it permanently nonmagical (if the item is a one-use item). The item (or its wielder, if the item is attended) can resist this effect with a DC 23 Will save. Damage dealt to an item is applied after the effects of magic drain are applied. The save DC is Charisma-based.

Nightwalker

This towering, night-black giant has demonic features, including a huge pair of ram-like horns. Its arms end in massive blades.

The most commonly encountered nightshade is the giant-like nightwalker. This powerful foe leads armies of undead against the living, but unlike most mortal generals the nightwalker is not content to stand back and observe the battles from safety. The undead creature is ever eager to put its tactics and plans to the test itself, and takes part in battles in every possible occurrence save for those that the creature has determined are self-destructive. This is not to say that the nightwalker never sacrifices its troops to gain a tactical advantage—just that these attacks are the only ones the monster feels no urge to participate in directly. Nightwalkers enjoy inflicting despair before death, particularly by destroying valued objects or murdering loved ones before delivering the final blow to a foe. A nightwalker is 20 feet tall and weighs 5,000 pounds.

No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

     Undead are once-living creatures animated by spiritual or supernatural forces. An undead creature has the following traits (unless otherwise noted in a creature’s entry).
   • No Constitution score. undead use their Charisma score in place of their Constitution score when calculating hit points, Fortitude saves, and any special ability that relies on Constitution (such as when calculating a breath weapon’s DC).
   • Cannot heal damage on its own if it has no Intelligence score, although it can be healed. Negative energy such as an inflict spell can heal undead creatures. The fast healing special quality works regardless of the creature’s Intelligence score.
   • Not affected by raise dead and reincarnate spells or abilities. Resurrection and true resurrection can affect undead creatures. These spells turn undead creatures back into the living creatures they were before becoming undead.
   • Proficient with its natural weapons, all simple weapons, and any weapons mentioned in its entry.
   • Proficient with whatever type of armor (light, medium, or heavy) it is described as wearing, as well as all lighter types. Undead not indicated as wearing armor are not proficient with armor. Undead are proficient with shields if they are proficient with any form of armor.
   • Undead do not breathe, eat, or sleep.

 Init +2; Senses darksense, darkvision 60 ft., detect magic, low-light vision; Perception +29

     Darkvision is the extraordinary ability to see with no light source at all, out to a range specified. Darkvision is black-and-white only (colors cannot be discerned). It does not allow creatures to see anything that they could not see otherwise—invisible objects are still invisible, and illusions are still visible as what they seem to be. Likewise, darkvision subjects a creature to gaze attacks normally. The presence of light does not spoil darkvision.

     A creature with low-light vision can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of dim light. It retains the ability to distinguish color and detail under these conditions.

 DR 15/good and silver; Immune cold, undead traits; SR 27

   • Immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).
   • Immunity to bleed, death effects, disease, paralysis, poison, sleep effects, and stunning.
   • Not subject to nonlethal damage, ability drain, or energy drain. Immune to damage to its physical ability scores (Constitution, Dexterity, and Strength), as well as to exhaustion and fatigue effects.
   • Immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).
   • Not at risk of death from massive damage, but is immediately destroyed when reduced to 0 hit points.

     A creature with DR ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below. 
     The entry indicates the amount of damage ignored and the type of weapon that negates the ability. 
     Some monsters are vulnerable to piercing, bludgeoning, or slashing damage. Others are vulnerable to certain materials, such as adamantine, alchemical silver, or cold-forged iron. Attacks from weapons that are not of the correct type or made of the correct material have their damage reduced, although a high enhancement bonus can overcome some forms of damage reduction. 
     Some monsters are vulnerable to magic weapons. Any weapon with at least a +1 magical enhancement bonus on attack and damage rolls overcomes the damage reduction of these monsters. Such creatures’ natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction. 
     A few very powerful monsters are vulnerable only to epic weapons—that is, magic weapons with at least a +6 enhancement bonus. Such creatures’ natural weapons are also treated as epic weapons for the purpose of overcoming damage reduction. 
     Some monsters are vulnerable to good-, evil-, chaotically, or lawfully aligned weapons. When a cleric or inquisitor casts align weapon, affected weapons might gain one or more of these properties, and certain magic weapons have these properties as well. A creature with an alignment subtype (chaotic, evil, good, or lawful) can overcome this type of damage reduction with its natural weapons and weapons it wields as if the weapons or natural weapons had an alignment (or alignments) that matched the subtype(s) of the creature. 
     When a damage reduction entry has a — after the slash, no weapon negates the damage reduction. 
     A few creatures are harmed by more than one kind of weapon. A weapon that inflicts damage of either type overcomes this damage reduction. 
     A few other creatures require combinations of different types of attacks to overcome their damage reduction, and a weapon must be both types to overcome this type of damage reduction. A weapon that is only one type is still subject to damage reduction.

     A creature with immunities takes no damage from listed sources. Immunities can also apply to afflictions, conditions, spells (based on school, level, or save type), and other effects. A creature that is immune does not suffer from these effects, or any secondary effects that are triggered due to an immune effect.

     A creature with Spell Resistance has the extraordinary ability to avoid the effects of spells and spell-like abilities that directly affect it. To determine if a spell or spell-like ability works against a creature with spell resistance, the caster must make a caster level check (1d20 + caster level). If the result equals or exceeds the creature’s spell resistance, the spell works normally, although the creature is still allowed a saving throw.

 Special Attacks channel energy (8d6, DC 29, 8/day), fear gaze, swift sundering

 Gaze (Su) A Gaze attack takes effect automatically when foes look at the attacking creature’s eyes. The typical range is 30 feet, but check the creature’s entry for details. A successful saving throw negates the effect. Each opponent within range of a gaze attack must attempt a saving throw each round at the beginning of his or her turn in the initiative order. Only looking directly at a creature with a gaze attack leaves an opponent vulnerable. Opponents can avoid the need to make the saving throw by not looking at the creature, in one of two ways. 
     Averting Eyes: The opponent avoids looking at the creature’s face, instead looking at its body, watching its shadow, tracking it in a reflective surface, etc. Each round, the opponent has a 50% chance to avoid having to make a saving throw against the gaze attack. The creature with the gaze attack, however, gains concealment (20% miss chance) against that opponent. 
     Wearing a Blindfold: The foe cannot see the creature at all (also possible to achieve by turning one’s back on the creature or shutting one’s eyes). The creature with the gaze attack gains total concealment (50% miss chance) against the opponent. 
     A creature with a gaze attack can also actively gaze as an attack action by choosing a target within range. That opponent must attempt a saving throw but can try to avoid this as described above. Thus, it is possible for an opponent to save against a creature’s gaze twice during the same round, once before the opponent’s action and once during the creature’s turn. 
     Gaze attacks can affect ethereal opponents. A creature is immune to gaze attacks of others of its kind unless otherwise noted. Allies of a creature with a gaze attack might be affected. All the creature’s allies are considered to be averting their eyes from the creature with the gaze attack, and have a 50% chance to not need to make a saving throw against the gaze attack each round. The creature can also veil its eyes, thus negating its gaze ability.

 Spell-Like Abilities (CL 16th; concentration +21)

     Spell-like abilities are magical and work just like spells (though they are not spells and so have no verbal, somatic, focus, or material components). They go away in an antimagic field and are subject to spell resistance if the spell the ability is based on would be subject to spell resistance.
     A spell-like ability usually has a limit on how often it can be used. A constant spell-like ability or one that can be used at will has no use limit; unless otherwise stated, a creature can only use a constant spell-like ability on itself. Reactivating a constant spell-like ability is a swift action. Using all other spell-like abilities is a standard action unless noted otherwise, and doing so provokes attacks of opportunity. It is possible to make a concentration check to use a spell-like ability defensively and avoid provoking an attack of opportunity, just as when casting a spell. A spell-like ability can be disrupted just as a spell can be. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled.
     For creatures with spell-like abilities, a designated caster level defines how difficult it is to dispel their spell-like effects and to define any level-dependent variables (such as range and duration) the abilities might have. The creature’s caster level never affects which spell-like abilities the creature has; sometimes the given caster level is lower than the level a spellcasting character would need to cast the spell of the same name. If no caster level is specified, the caster level is equal to the creature’s Hit Dice. The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Charisma modifier.
     Some spell-like abilities duplicate spells that work differently when cast by characters of different classes. A monster’s spell-like abilities are presumed to be the sorcerer/wizard versions. If the spell in question is not a sorcerer/wizard spell, then default to cleric, druid, bard, paladin, and ranger, in that order.

 1/day—cone of cold (DC 20), finger of death (DC 22), plane shift (DC 22), summon (level 7, 4 greater shadows)

     A creature with the Summon SLA can summon other specific creatures of its kind much as though casting a summon monster spell, but it usually has only a limited chance of success (as specified in the creature’s entry). Roll d%: On a failure, no creature answers the summons. Summoned creatures automatically return whence they came after 1 hour. A creature summoned in this way cannot use any spells or spell-like abilities that require material components costing more than 1 gp unless those components are supplied, nor can it use its own summon ability for 1 hour. An appropriate spell level is given for each summoning ability for purposes of Will saves, caster level checks, and concentration checks. No experience points are awarded for defeating summoned monsters.

 Base Atk +15; CMB +29; CMD 41

     When performing a combat maneuver, you must use an action appropriate to the maneuver you are attempting to perform. While many combat maneuvers can be performed as part of an attack action, full-attack action, or attack of opportunity (in place of a melee attack), others require a specific action. Unless otherwise noted, performing a combat maneuver provokes an attack of opportunity from the target of the maneuver. If you are hit by the target, you take the damage normally and apply that amount as a penalty to the attack roll to perform the maneuver. If your target is immobilized, unconscious, or otherwise incapacitated, your maneuver automatically succeeds (treat as if you rolled a natural 20 on the attack roll). If your target is stunned, you receive a +4 bonus on your attack roll to perform a combat maneuver against it.
     When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target’s Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.
     If your attack roll equals or exceeds the CMD of the target, your maneuver is a success and has the listed effect. Some maneuvers, such as bull rush, have varying levels of success depending on how much your attack roll exceeds the target’s CMD. Rolling a natural 20 while attempting a combat maneuver is always a success (except when attempting to escape from bonds), while rolling a natural 1 is always a failure.

Nightcrawler

This immense worm is covered with plates of dead-black, chitinous armor. Its toothy maw yawns like a cave.

Although the nightcrawler might appear to be little more than an immense and frightening vermin, with its centipede-like body and numerous glowing eyes, it is actually incredibly intelligent. When not cleansing the deep caverns of life, the nightcrawler spends its time plotting how best to carry out its own private stages of the overall nightshade plan to expunge life from all worlds, conferring with its undead minions and, when necessary, observing living creatures from afar while invisible to learn about hidden enclaves that its depredations might otherwise have missed. It would be one thing if the nightcrawlers remained in the deep caverns, for these regions are rife with foul life the world is better off without. Yet unfortunately for those who dwell upon the surface, nightcrawlers often crawl up through the tunnels to bring their devastation to the night above. Although they always retreat underground before the first tentative rays of dawn color the eastern skies, they can spread an incredible amount of ruin in the span of a few short hours each night. A nightcrawler is 60 feet long and weighs 10,000 pounds.

 CE Gargantuan undead (extraplanar, nightshade)

     The Extraplanar subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

     A creature with tremorsense is sensitive to vibrations in the ground and can automatically pinpoint the location of anything that is in contact with the ground. Aquatic creatures with tremorsense can also sense the location of creatures moving through water. This does not allow the creature to ignore any miss chance for concealment that would otherwise apply.

 Grab (Ex) If this creature hits with the indicated attack it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its CMB check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature’s descriptive text).
     Creatures with the grab special attack receive a +4 bonus on combat maneuver checks made to start and maintain a grapple.
     Unless otherwise noted, grab can only be used against targets of a size equal to or smaller than the creature with this ability. If the creature can use grab on creatures of other sizes, it is noted in the creature’s Special Attacks line.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

 Special Attacks channel negative energy (9d6, DC 31, 9/day), energy drain (1 level, DC 28), swallow whole (4d10+22 bludgeoning plus energy drain, AC 23, 31 hp)

     Energy Drain supernaturally saps a living opponent’s vital energy and happens automatically when a melee or ranged attack hits. Each successful energy drain bestows one or more negative levels (the creature’s description specifies how many) with no saving throw. If an attack that includes an energy drain scores a critical hit, it bestows twice the listed number of negative levels. Unless otherwise specified in the creature’s description, a draining creature gains 5 temporary hit points for each negative level it bestows on an opponent. These temporary hit points last for a maximum of 1 hour. Negative levels remain until 24 hours have passed or until they are removed with a spell such as restoration. If a negative level is not removed before 24 hours have passed, the affected creature must attempt a Fortitude save (DC 10 + 1/2 the draining creature’s racial HD + the draining creature’s Cha modifier; the exact DC is given in the creature’s descriptive text). On a success, the negative level goes away with no harm to the creature. On a failure, the negative level becomes permanent. A separate saving throw is required for each negative level. 

 Swallow Whole (Ex) If this creature begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. Unless otherwise noted, the opponent can be up to one size category smaller than the swallowing creature. Being swallowed causes a creature to take damage each round. The amount and type of damage varies and is given in the creature’s statistics. A swallowed creature keeps the grappled condition, while the creature that did the swallowing does not. A swallowed creature can try to cut its way free with any light slashing or piercing weapon (the amount of cutting damage required to get free is equal to 1/10 the creature’s total hit points), or it can just try to escape the grapple. The Armor Class of the interior of a creature that swallows whole is normally 10 + 1/2 its natural armor bonus, with no modifiers for size or Dexterity. If a swallowed creature cuts its way out, the swallowing creature cannot use  swallow whole again until the damage is healed. If the swallowed creature escapes the grapple, success puts it back in the attacker’s mouth, where it may be bitten or swallowed again.
     If this creature hits with the indicated attack it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the grab to hold the opponent.

If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature’s descriptive text).
     Creatures with the grab special attack receive a +4 bonus on combat maneuver checks made to start and maintain a grapple.
     Unless otherwise noted, grab can only be used against targets of a size equal to or smaller than the creature with this ability. If the creature can use grab on creatures of other sizes, it is noted in the creature’s Special Attacks line.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so.

While many combat maneuvers can be performed as part of an attack action, full-attack action, or attack of opportunity (in place of a melee attack), others require a specific action. Unless otherwise noted, performing a combat maneuver provokes an attack of opportunity from the target of the maneuver. If you are hit by the target, you take the damage normally and apply that amount as a penalty to the attack roll to perform the maneuver. If your target is immobilized, unconscious, or otherwise incapacitated, your maneuver automatically succeeds (treat as if you rolled a natural 20 on the attack roll). If your target is stunned, you receive a +4 bonus on your attack roll to perform a combat maneuver against it.
     When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target’s Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.
     If your attack roll equals or exceeds the CMD of the target, your maneuver is a success and has the listed effect. Some maneuvers, such as bull rush, have varying levels of success depending on how much your attack roll exceeds the target’s CMD. Rolling a natural 20 while attempting a combat maneuver is always a success (except when attempting to escape from bonds), while rolling a natural 1 is always a failure.

Nightwave

Immense almost beyond belief, this sleek, midnight-black shark rises from the sea like an unholy island heaved up from below.

The most powerful of the known types of nightshade is the ravenous nightwave, an unholy personification of the remorseless gluttony of death given the form of a shark the size of the largest whales. Although the nightwave is most at home in the ocean’s deeps, it has no need to breathe, and its constant fly spell-like ability allows it to bring ruin above the waves as the need presents itself. A nightwave is 100 feet long and weighs 200 tons.

CR 20 XP 307,200

 CE Colossal undead (aquatic, extraplanar, nightshade)

     The Extraplanar subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

     Undead are once-living creatures animated by spiritual or supernatural forces. An undead creature has the following traits (unless otherwise noted in a creature’s entry).
   • No Constitution score. undead use their Charisma score in place of their Constitution score when calculating hit points, Fortitude saves, and any special ability that relies on Constitution (such as when calculating a breath weapon’s DC).
   • Cannot heal damage on its own if it has no Intelligence score, although it can be healed. Negative energy such as an inflict spell can heal undead creatures. The fast healing special quality works regardless of the creature’s Intelligence score.
   • Not affected by raise dead and reincarnate spells or abilities. Resurrection and true resurrection can affect undead creatures. These spells turn undead creatures back into the living creatures they were before becoming undead.
   • Proficient with its natural weapons, all simple weapons, and any weapons mentioned in its entry.
   • Proficient with whatever type of armor (light, medium, or heavy) it is described as wearing, as well as all lighter types. Undead not indicated as wearing armor are not proficient with armor. Undead are proficient with shields if they are proficient with any form of armor.
   • Undead do not breathe, eat, or sleep.

 Init +7; Senses darksense, darkvision 120 ft., detect magic, low-light vision; Perception +37

     Darkvision is the extraordinary ability to see with no light source at all, out to a range specified. Darkvision is black-and-white only (colors cannot be discerned). It does not allow creatures to see anything that they could not see otherwise—invisible objects are still invisible, and illusions are still visible as what they seem to be. Likewise, darkvision subjects a creature to gaze attacks normally. The presence of light does not spoil darkvision.

     A creature with low-light vision can see twice as far as a human in starlight, moonlight, torchlight, and similar conditions of dim light. It retains the ability to distinguish color and detail under these conditions.

 DR 15/good and silver; Immune cold, undead traits; SR 29

   • Immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).
   • Immunity to bleed, death effects, disease, paralysis, poison, sleep effects, and stunning.
   • Not subject to nonlethal damage, ability drain, or energy drain. Immune to damage to its physical ability scores (Constitution, Dexterity, and Strength), as well as to exhaustion and fatigue effects.
   • Immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).
   • Not at risk of death from massive damage, but is immediately destroyed when reduced to 0 hit points.

     A creature with DR ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below. 
     The entry indicates the amount of damage ignored and the type of weapon that negates the ability. 
     Some monsters are vulnerable to piercing, bludgeoning, or slashing damage. Others are vulnerable to certain materials, such as adamantine, alchemical silver, or cold-forged iron. Attacks from weapons that are not of the correct type or made of the correct material have their damage reduced, although a high enhancement bonus can overcome some forms of damage reduction. 
     Some monsters are vulnerable to magic weapons. Any weapon with at least a +1 magical enhancement bonus on attack and damage rolls overcomes the damage reduction of these monsters. Such creatures’ natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction. 
     A few very powerful monsters are vulnerable only to epic weapons—that is, magic weapons with at least a +6 enhancement bonus. Such creatures’ natural weapons are also treated as epic weapons for the purpose of overcoming damage reduction. 
     Some monsters are vulnerable to good-, evil-, chaotically, or lawfully aligned weapons. When a cleric or inquisitor casts align weapon, affected weapons might gain one or more of these properties, and certain magic weapons have these properties as well. A creature with an alignment subtype (chaotic, evil, good, or lawful) can overcome this type of damage reduction with its natural weapons and weapons it wields as if the weapons or natural weapons had an alignment (or alignments) that matched the subtype(s) of the creature. 
     When a damage reduction entry has a — after the slash, no weapon negates the damage reduction. 
     A few creatures are harmed by more than one kind of weapon. A weapon that inflicts damage of either type overcomes this damage reduction. 
     A few other creatures require combinations of different types of attacks to overcome their damage reduction, and a weapon must be both types to overcome this type of damage reduction. A weapon that is only one type is still subject to damage reduction.

     A creature with immunities takes no damage from listed sources. Immunities can also apply to afflictions, conditions, spells (based on school, level, or save type), and other effects. A creature that is immune does not suffer from these effects, or any secondary effects that are triggered due to an immune effect.

     A creature with Spell Resistance has the extraordinary ability to avoid the effects of spells and spell-like abilities that directly affect it. To determine if a spell or spell-like ability works against a creature with spell resistance, the caster must make a caster level check (1d20 + caster level). If the result equals or exceeds the creature’s spell resistance, the spell works normally, although the creature is still allowed a saving throw.

 Weaknesses light aversion

 OFFENSE

 Speed fly 60 ft. (good), swim 60 ft.

     A creature with a Fly speed can cease or resume flight as a free action on their turn. Without making a check, a flying creature can remain flying at the end of its turn so long as it moves a distance greater than half its speed. It can also turn up to 45 degrees during its turn by sacrificing 5 feet of movement, can rise at half speed at an angle of 45 degrees (ignoring the penalty for diagonal movement), and can descend at any angle at normal speed. At the beginning of their turn a flying creature can move in a different direction than they did previously without needing a Fly check.
     A creature with a natural fly speed receives a bonus (or penalty) on Fly skill checks depending on its maneuverability:
 • Clumsy –8
 • Poor –4
 • Average +0
 • Good +4
 • Perfect +8
     Creatures without a maneuverability rating are assumed to have average maneuverability and take no penalty on Fly checks. These modifiers are already included in the creature’s statblock.

     A creature with a Swim speed can move through water at its indicated speed without making Swim checks. It gains a +8 racial bonus on any Swim check to perform a special action or avoid a hazard. The creature can always choose to take 10 on a Swim check, even if distracted or endangered when swimming. Such a creature can use the run action while swimming, provided that it swims in a straight line.

 Melee bite +35 (5d10+22/19–20 plus 4d6 cold, energy drain, and grab), tail slap +30 (4d8+12/19–20 plus 4d6 cold)

 Grab (Ex) If this creature hits with the indicated attack it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its CMB check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature’s descriptive text).
     Creatures with the grab special attack receive a +4 bonus on combat maneuver checks made to start and maintain a grapple.
     Unless otherwise noted, grab can only be used against targets of a size equal to or smaller than the creature with this ability. If the creature can use grab on creatures of other sizes, it is noted in the creature’s Special Attacks line.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

 Space 30 ft.; Reach 30 ft.

 Special Attacks channel energy (10d6, DC 33, 10/day), energy drain (2 levels, DC 31), swallow whole (5d10+28 bludgeoning plus energy drain, AC 25, 39 hp)

     Energy Drain supernaturally saps a living opponent’s vital energy and happens automatically when a melee or ranged attack hits. Each successful energy drain bestows one or more negative levels (the creature’s description specifies how many) with no saving throw. If an attack that includes an energy drain scores a critical hit, it bestows twice the listed number of negative levels. Unless otherwise specified in the creature’s description, a draining creature gains 5 temporary hit points for each negative level it bestows on an opponent. These temporary hit points last for a maximum of 1 hour. Negative levels remain until 24 hours have passed or until they are removed with a spell such as restoration. If a negative level is not removed before 24 hours have passed, the affected creature must attempt a Fortitude save (DC 10 + 1/2 the draining creature’s racial HD + the draining creature’s Cha modifier; the exact DC is given in the creature’s descriptive text). On a success, the negative level goes away with no harm to the creature. On a failure, the negative level becomes permanent. A separate saving throw is required for each negative level. 

 Swallow Whole (Ex) If this creature begins its turn with an opponent grappled in its mouth (see Grab), it can attempt a new combat maneuver check (as though attempting to pin the opponent). If it succeeds, it swallows its prey, and the opponent takes bite damage. Unless otherwise noted, the opponent can be up to one size category smaller than the swallowing creature. Being swallowed causes a creature to take damage each round. The amount and type of damage varies and is given in the creature’s statistics. A swallowed creature keeps the grappled condition, while the creature that did the swallowing does not. A swallowed creature can try to cut its way free with any light slashing or piercing weapon (the amount of cutting damage required to get free is equal to 1/10 the creature’s total hit points), or it can just try to escape the grapple. The Armor Class of the interior of a creature that swallows whole is normally 10 + 1/2 its natural armor bonus, with no modifiers for size or Dexterity. If a swallowed creature cuts its way out, the swallowing creature cannot use  swallow whole again until the damage is healed. If the swallowed creature escapes the grapple, success puts it back in the attacker’s mouth, where it may be bitten or swallowed again.
     If this creature hits with the indicated attack it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its CMB check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature’s descriptive text).
     Creatures with the grab special attack receive a +4 bonus on combat maneuver checks made to start and maintain a grapple.
     Unless otherwise noted, grab can only be used against targets of a size equal to or smaller than the creature with this ability. If the creature can use grab on creatures of other sizes, it is noted in the creature’s Special Attacks line.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

 Spell-Like Abilities (CL 20th; concentration +27)

     Spell-like abilities are magical and work just like spells (though they are not spells and so have no verbal, somatic, focus, or material components). They go away in an antimagic field and are subject to spell resistance if the spell the ability is based on would be subject to spell resistance.
     A spell-like ability usually has a limit on how often it can be used. A constant spell-like ability or one that can be used at will has no use limit; unless otherwise stated, a creature can only use a constant spell-like ability on itself. Reactivating a constant spell-like ability is a swift action. Using all other spell-like abilities is a standard action unless noted otherwise, and doing so provokes attacks of opportunity. It is possible to make a concentration check to use a spell-like ability defensively and avoid provoking an attack of opportunity, just as when casting a spell. A spell-like ability can be disrupted just as a spell can be. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled.
     For creatures with spell-like abilities, a designated caster level defines how difficult it is to dispel their spell-like effects and to define any level-dependent variables (such as range and duration) the abilities might have. The creature’s caster level never affects which spell-like abilities the creature has; sometimes the given caster level is lower than the level a spellcasting character would need to cast the spell of the same name. If no caster level is specified, the caster level is equal to the creature’s Hit Dice. The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Charisma modifier.
     Some spell-like abilities duplicate spells that work differently when cast by characters of different classes. A monster’s spell-like abilities are presumed to be the sorcerer/wizard versions. If the spell in question is not a sorcerer/wizard spell, then default to cleric, druid, bard, paladin, and ranger, in that order.

 Constant—detect magic, magic fang, see invisibility

 At will—confusion (DC 21), contagion (DC 21), deeper darkness, greater dispel magic, invisibility, unholy blight (DC 21)

 1/day—mass hold monster (DC 26), plane shift (DC 24), summon (level 9, 1 nightwing), wail of the banshee (DC 26)

     A creature with the Summon SLA can summon other specific creatures of its kind much as though casting a summon monster spell, but it usually has only a limited chance of success (as specified in the creature’s entry). Roll d%: On a failure, no creature answers the summons. Summoned creatures automatically return whence they came after 1 hour. A creature summoned in this way cannot use any spells or spell-like abilities that require material components costing more than 1 gp unless those components are supplied, nor can it use its own summon ability for 1 hour. An appropriate spell level is given for each summoning ability for purposes of Will saves, caster level checks, and concentration checks. No experience points are awarded for defeating summoned monsters.

 Blackest Depths (Su) The waters in which a nightwave swims become as chill, dark, and heavy as those in the ocean’s deepest reaches. All waters within 60 feet are completely dark (as deeper darkness), and creatures within this radius take 6d6 points of damage (half cold, half bludgeoning) at the end of their turn each round if they remain in the area at this time. A DC 31 Fortitude save negates the crushing damage. Incorporeal creatures and creatures with the aquatic or water subtypes native to deep waters do not take this damage, and freedom of movement protects completely against the damage. Any magical light effect within this radius at the beginning of the nightwave’s turn is dispelled (treat as greater dispel magic). This effect does not extend out of the water. The save DC is Charisma-based.

Oblivion

A single sinister eye glares from the heart of this roiling cloud of darkness as tentacles of smoke coil and writhe beneath it.

Rare and powerful denizens of the Negative Energy Plane, oblivions are void and nothingness given terrible will. They lurk among crystalline sheets of accumulated entropy that line their home plane’s darkest interior, hungering to unmake the walls of reality and drag all of the cosmos down to its eventual end, allowing themselves to also finally end. Once unleashed upon mortal worlds, oblivions crisscross the globe, destroying its denizens and laying waste to the land until destroyed themselves or until they strip a planet bare of substance, life, and heat. Despite its vast bulk, a single oblivion must often dedicate years or even centuries to ending a world, and each is so adept at scrubbing away all traces a being leaves upon the cosmos that people, nations, and entire worlds annihilated by an oblivion are soon forgotten by outsiders. Some gods claim that the brutal efficiency of the oblivions are intended to someday be released upon the multiverse to cleanse away creation so a new cycle of life can begin from chaotic nothing, while other deities insist the oblivions’ work is nearly complete, leaving only isolated specks of life floating in a vast, unfeeling void. Unlike nightshades or other noteworthy denizens of their dark realm, oblivions serve no masters or agendas. They believe themselves to be the way all things must end. Though cunning, they rarely find reason to communicate with other creatures, leaving much of their motives, origins, and philosophy in the cosmos a mystery. Like grim doll makers, oblivions can recreate slain victims from their own dark substance, transforming a world’s heroes and villains into hollow pawns they can dispatch to slay would-be heroes or undermine organized resistance. Lacking any inherent ability to traverse the planes, most oblivions rely on such servants created in the shapes of powerful spellcasters or outsiders to provide routes to new worlds. These hollow reproductions know little of their masters’ will beyond sharing comfort in the coming end of days, and most desperately fill in the gaps with appealing philosophies. Some of the most powerful servants form doomsday cults on distant planets to prepare them for an oblivion’s arrival. Oblivions share a symbiosis with the artifacts known as spheres of annihilation, coveting their powerful, highly destructive magic. The towering oozes are unaffected by the artifact’s destructive powers, and can move them as easily as a child might carry a toy. Some speculate that the spheres are in fact the eggs or spores of these apocalyptic beings, as rare survivors recount tales of spheres spontaneously birthing the roiling, devouring entities. Oblivions typically measure several dozen feet across, though their presence corrupts and consumes life, making the roiling darkness that most people mistake for their bodies seem much larger. Despite their size, oblivions have no mass. Upon destruction, an oblivion collapses thunderously into nothing.

     An Ooze is an amorphous or mutable creature, usually mindless. An ooze has the following traits (unless otherwise noted in a creature’s entry).
   • Proficient with its natural weapons only.
   • Proficient with no armor.
   • Oozes eat and breathe, but do not sleep.

 Init +17; Senses blindsight 120 ft., see in darkness; Perception +17

     Using nonvisual senses, such as sensitivity to vibrations, keen smell, acute hearing, or echolocation, a creature with blindsight maneuvers and fights as well as a sighted creature. Invisibility, darkness, and most kinds of concealment are irrelevant, though the creature must have line of effect to a creature or object to discern that creature or object. The ability’s range is specified in the creature’s descriptive text. The creature usually does not need to make Perception checks to notice creatures within range of its blindsight ability. Unless noted otherwise, blindsight is continuous, and the creature need do nothing to use it. Some forms of blindsight, however, must be triggered as a free action. If so, this is noted in the creature’s description. If a creature must trigger its blindsight ability, the creature gains the benefits of blindsight only during its turn.

 See in Darkness (Su) This creature can see perfectly in darkness of any kind, including that created by deeper darkness.

 DEFENSE 

 AC 36, touch 15, flat-footed 23 (+13 Dex, +21 natural, –8 size) 

 hp 377 (26d8+260); regeneration 15 (positive energy or inspiration) 

      Regeneration is an extraordinary ability which makes a creature difficult to kill. Creatures with regeneration heal damage at a fixed rate but they cannot die as long as their regeneration is still functioning although creatures with regeneration still fall unconscious when their hit points are below 0. Regeneration does not restore hit points lost from starvation, suffocation, or thirst. Certain attack forms cause a creature’s regeneration to stop functioning on the round following the attack. During this round, the creature does not heal any damage and can die normally. The creature’s descriptive text describes the types of damage that cause the regeneration to cease functioning. 
      Attack forms that don’t deal hit point damage are not healed by regeneration. Regenerating creatures can regrow lost portions of their bodies and can reattach severed limbs or body parts if they are brought together within 1 hour of severing. Severed parts that are not reattached wither and die normally. 
      A creature must have a Constitution score to have the regeneration ability.

   • Immunity to poison, sleep effects, paralysis, polymorph, and stunning.
   • Not subject to critical hits or flanking. Does not take additional damage from precision-based attacks, such as sneak attack.

 Negative Energy Affinity (Ex) This creature is alive but is healed by negative energy and harmed by positive energy, as if it were an undead creature.

     A creature with DR ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below. 
     The entry indicates the amount of damage ignored and the type of weapon that negates the ability. 
     Some monsters are vulnerable to piercing, bludgeoning, or slashing damage. Others are vulnerable to certain materials, such as adamantine, alchemical silver, or cold-forged iron. Attacks from weapons that are not of the correct type or made of the correct material have their damage reduced, although a high enhancement bonus can overcome some forms of damage reduction. 
     Some monsters are vulnerable to magic weapons. Any weapon with at least a +1 magical enhancement bonus on attack and damage rolls overcomes the damage reduction of these monsters. Such creatures’ natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction.

A creature with an alignment subtype (chaotic, evil, good, or lawful) can overcome this type of damage reduction with its natural weapons and weapons it wields as if the weapons or natural weapons had an alignment (or alignments) that matched the subtype(s) of the creature. 
     When a damage reduction entry has a — after the slash, no weapon negates the damage reduction. 
     A few creatures are harmed by more than one kind of weapon. A weapon that inflicts damage of either type overcomes this damage reduction. 
     A few other creatures require combinations of different types of attacks to overcome their damage reduction, and a weapon must be both types to overcome this type of damage reduction. A weapon that is only one type is still subject to damage reduction.

     A creature with immunities takes no damage from listed sources. Immunities can also apply to afflictions, conditions, spells (based on school, level, or save type), and other effects. A creature that is immune does not suffer from these effects, or any secondary effects that are triggered due to an immune effect.

     A creature with resistance to energy ignores some damage of a certain type per attack, but it does not have total immunity. Each resistance ability is defined by what energy type it resists and how many points of damage are resisted. It doesn’t matter whether the damage has a mundane or magical source. When resistance completely negates the damage from an energy attack, the attack does not disrupt spellcasting. This resistance does not stack with the resistance that a spell might provide.

     A creature with Spell Resistance has the extraordinary ability to avoid the effects of spells and spell-like abilities that directly affect it. To determine if a spell or spell-like ability works against a creature with spell resistance, the caster must make a caster level check (1d20 + caster level). If the result equals or exceeds the creature’s spell resistance, the spell works normally, although the creature is still allowed a saving throw.

 Speed 30 ft., burrow 30 ft., fly 30 ft. (perfect) 

     A creature with a Burrow speed can tunnel through dirt, but not through rock unless the descriptive text says otherwise. Creatures cannot charge or run while burrowing. Most burrowing creatures do not leave behind tunnels other creatures can use (either because the material they tunnel through fills in behind them or because they do not actually dislocate any material when burrowing).

     A creature with a Fly speed can cease or resume flight as a free action on their turn. Without making a check, a flying creature can remain flying at the end of its turn so long as it moves a distance greater than half its speed. It can also turn up to 45 degrees during its turn by sacrificing 5 feet of movement, can rise at half speed at an angle of 45 degrees (ignoring the penalty for diagonal movement), and can descend at any angle at normal speed. At the beginning of their turn a flying creature can move in a different direction than they did previously without needing a Fly check.
     A creature with a natural fly speed receives a bonus (or penalty) on Fly skill checks depending on its maneuverability:
 • Clumsy –8
 • Poor –4
 • Average +0
 • Good +4
 • Perfect +8
     Creatures without a maneuverability rating are assumed to have average maneuverability and take no penalty on Fly checks. These modifiers are already included in the creature’s statblock.

 Melee 4 slams +27 (2d8+16/19–20 plus 2d6 negative energy and grab) 

 Grab (Ex) If this creature hits with the indicated attack it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. The creature has the option to conduct the grapple normally, or simply use the part of its body it used in the grab to hold the opponent. If it chooses to do the latter, it takes a –20 penalty on its CMB check to make and maintain the grapple, but does not gain the grappled condition itself. A successful hold does not deal any extra damage unless the creature also has the constrict special attack. If the creature does not constrict, each successful grapple check it makes during successive rounds automatically deals the damage indicated for the attack that established the hold. Otherwise, it deals constriction damage as well (the amount is given in the creature’s descriptive text).
     Creatures with the grab special attack receive a +4 bonus on combat maneuver checks made to start and maintain a grapple.
     Unless otherwise noted, grab can only be used against targets of a size equal to or smaller than the creature with this ability. If the creature can use grab on creatures of other sizes, it is noted in the creature’s Special Attacks line.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

 Special Attacks annihilation, constrict (4d8+24), servants of entropy 

 Constrict (Ex) This creature deals bludgeoning damage by crushing its opponent whenever it makes a successful grapple check (including the initial check to establish the grapple). It still receives any other benefits of a successful check, including dealing additional damage. The amount of damage is given in the creature’s entry and is typically equal to the amount of damage caused by the creature’s melee attack. This is an extraordinary ability.
     A grappled creature is restrained by a creature, trap, or effect. Grappled creatures cannot move and take a –4 penalty to Dexterity. A grappled creature takes a –2 penalty on all attack rolls and combat maneuver checks, except those made to grapple or escape a grapple. In addition, grappled creatures can take no action that requires two hands to perform. A grappled character who attempts to cast a spell or use a spell-like ability must make a concentration check (DC 10 + grappler’s CMB + spell level), or lose the spell. Grappled creatures cannot make attacks of opportunity.
     A grappled creature cannot use Stealth to hide from the creature grappling it, even if a special ability, such as hide in plain sight, would normally allow it to do so. If a grappled creature becomes invisible, through a spell or other ability, it gains a +2 circumstance bonus on its CMD to avoid being grappled, but receives no other benefit.

 Spell-Like Abilities (CL 20th; concentration +25) 

     Spell-like abilities are magical and work just like spells (though they are not spells and so have no verbal, somatic, focus, or material components). They go away in an antimagic field and are subject to spell resistance if the spell the ability is based on would be subject to spell resistance.
     A spell-like ability usually has a limit on how often it can be used. A constant spell-like ability or one that can be used at will has no use limit; unless otherwise stated, a creature can only use a constant spell-like ability on itself. Reactivating a constant spell-like ability is a swift action. Using all other spell-like abilities is a standard action unless noted otherwise, and doing so provokes attacks of opportunity. It is possible to make a concentration check to use a spell-like ability defensively and avoid provoking an attack of opportunity, just as when casting a spell. A spell-like ability can be disrupted just as a spell can be. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled.
     For creatures with spell-like abilities, a designated caster level defines how difficult it is to dispel their spell-like effects and to define any level-dependent variables (such as range and duration) the abilities might have. The creature’s caster level never affects which spell-like abilities the creature has; sometimes the given caster level is lower than the level a spellcasting character would need to cast the spell of the same name. If no caster level is specified, the caster level is equal to the creature’s Hit Dice. The saving throw (if any) against a spell-like ability is 10 + the level of the spell the ability resembles or duplicates + the creature’s Charisma modifier.
     Some spell-like abilities duplicate spells that work differently when cast by characters of different classes. A monster’s spell-like abilities are presumed to be the sorcerer/wizard versions. If the spell in question is not a sorcerer/wizard spell, then default to cleric, druid, bard, paladin, and ranger, in that order.

 Base Atk +19; CMB +43; CMD 66 

     When performing a combat maneuver, you must use an action appropriate to the maneuver you are attempting to perform. While many combat maneuvers can be performed as part of an attack action, full-attack action, or attack of opportunity (in place of a melee attack), others require a specific action. Unless otherwise noted, performing a combat maneuver provokes an attack of opportunity from the target of the maneuver. If you are hit by the target, you take the damage normally and apply that amount as a penalty to the attack roll to perform the maneuver. If your target is immobilized, unconscious, or otherwise incapacitated, your maneuver automatically succeeds (treat as if you rolled a natural 20 on the attack roll). If your target is stunned, you receive a +4 bonus on your attack roll to perform a combat maneuver against it.
     When you attempt to perform a combat maneuver, make an attack roll and add your CMB in place of your normal attack bonus. Add any bonuses you currently have on attack rolls due to spells, feats, and other effects. These bonuses must be applicable to the weapon or attack used to perform the maneuver. The DC of this maneuver is your target’s Combat Maneuver Defense. Combat maneuvers are attack rolls, so you must roll for concealment and take any other penalties that would normally apply to an attack roll.
     If your attack roll equals or exceeds the CMD of the target, your maneuver is a success and has the listed effect. Some maneuvers, such as bull rush, have varying levels of success depending on how much your attack roll exceeds the target’s CMD. Rolling a natural 20 while attempting a combat maneuver is always a success (except when attempting to escape from bonds), while rolling a natural 1 is always a failure.

It is possible to address multiple creatures at once telepathically, although maintaining a telepathic conversation with more than one creature at a time is just as difficult as simultaneously speaking and listening to multiple people at the same time.

 SPECIAL ABILITIES

 Annihilation (Su) Any spaces an oblivion moves through are left fallow and lifeless in its wake. Ground that it moves over using its base speed becomes barren and is treated as if affected by a diminish plants spell to stunt growth. Dead bodies that the oblivion moves through immediately crumble into dust. Any constrict damage an oblivion deals to a creature automatically bypasses all damage reduction. A creature reduced to 0 or fewer hit points by this constrict damage is immediately slain and its remains (but not its gear) are disintegrated. Once per round as a free action, an oblivion can target a single object in its space. A nonmagical object so targeted is immediately destroyed. A magical item must succeed at a DC 33 Fortitude save or be destroyed. The save DC is Constitution-based. 

 Aura of Dubiety (Su) An oblivion’s presence is anathema to the gods and the forces that bind creation together. Its presence warps divine magic and severs living beings from the power of life. Any living creature that begins its turn within range of an oblivion’s Aura of dubiety takes 2d6 points of negative energy damage. This negative energy has no beneficial effect on undead. A creature attempting to cast a divine spell within 60 feet of an oblivion must succeed at a concentration check as if casting defensively (DC = 15 + double the spell level) or the spell is automatically subverted, allowing the oblivion to decide the spell’s target and effect as if it were the original caster. If the affected spell uses positive energy, the subverted spell instead uses negative energy.

 Immunity to Annihilation (Ex) An oblivion is immune to destruction spells, disintegrate effects, spheres of annihilation, and similar effects that completely destroy living creatures.

 Immunity to Banishment (Ex) An oblivion is never treated as having the extraplanar subtype, regardless of what plane it currently inhabits, rendering it immune to banishment, dismissal, and similar effects. In addition to this, effects that force the oblivion onto another plane (such as plane shift or the violet beam of a prismatic spray) do not function against an oblivion unless the effect comes from an artifact, a creature capable of granting spells to its worshipers, or a mythic source.

     The Extraplanar subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

 Master of Annihilation (Ex) An oblivion can establish control over a sphere of annihilation  as far away as 100 feet. When an oblivion controls a sphere of annihilation, it does so through force of will and an inborn understanding of the sphere’s reality—the oblivion’s control check is 1d20 + the oblivion’s Hit Dice + its Charisma modifier (the typical oblivion has a control check bonus of +31, and thus can never fail to control a sphere of annihilation unless control of the sphere is opposed). When an oblivion establishes control, it can maintain control at a distance of 100 feet + 20 feet per Hit Die (620 feet for the typical oblivion), and the sphere’s speed under the oblivion’s control is 20 feet + 5 feet for every 5 points by which the oblivion’s control check result in that round exceeded 30.

 Servants of Entropy (Su) As a full-round action, an oblivion can reform any living creature it has slain within the past hour, forging an obedient duplicate from its own dark mass. Servants created in this manner are identical to their original forms, with all their associated memories, racial abilities, and class abilities, except the duplicate loses any divine spellcasting ability its original form had. A servant’s alignment changes to neutral evil, its type changes to native outsider (do not recalculate hit points, saving throws, or similar abilities), and it gains negative energy affinity. An oblivion can communicate telepathically with its servants anywhere   on the same plane and can destroy a servant as a free action. An oblivion can manifest a total number of Hit Dice worth of servants equal to twice its own Hit Dice (52 for a typical oblivion), but no single servant can have more Hit Dice than the oblivion’s CR. An oblivion cannot manifest more than one copy of any given creature at one time.

 Susceptible to Creation (Ex) An oblivion is a manifestation of disbelief and decay, and the forces of compassion and creativity are anathema to it. It is vulnerable to positive energy, taking damage as if it were undead, though it retains its control over any divine spells, allowing it to often usurp and corrupt cure spells and similar curative magic. An oblivion loses its regeneration any round in which it either takes damage from positive energy or is within 30 feet of a creature that succeeds at a DC 35 Perform check. Creatures under the effect of a good hope spell, an inspire courage bardic performance, or any spell effect of 5th level or higher that grants a morale bonus gain immunity to the negative energy damage dealt by an oblivion’s slams and Aura of dubiety.

 Talisman of the Sphere (Ex) The talisman of the sphere is anathema to an oblivion. A character who carries a talisman of the sphere can penetrate an oblivion’s damage reduction with ease, ignores its spell resistance, is immune to its aura, and gains a +10 bonus on saving throws against the oblivion’s special attacks and spell-like abilities.

Hundun

The wrinkled, blotchy skin of this giant hangs from its body like hooded robes, masking its face.

In the nightmare dimensions of unreality beyond space and time, the power of alien Gods is sufficient to give life to intention. Hunduns are the incarnation of the desire to reduce the multiverse to a space filled with nothing but randomly fluctuating energy fields and gravitic curvatures. Hunduns are primordial alien monks who embody aspects of the gaping, formless void that preceded the creation of the multiverse. They are out of step with reality, which accommodates their individual existences as intractable errors that must be continually accounted for yet that can never fully be corrected. These bizarre aberrations of life are sustained by negative energy—life’s antithetical force—yet they are not undead, nor do they differentiate between the living and the unliving in the pursuit of their purpose. Few beings can exist on the Negative Energy Plane for long, making the hunduns, who often make their homes there, something of an anomaly. Some scholars speculate that early hunduns came to the Negative Energy Plane as explorers, and remained there, addicted to the mixture of pain and euphoric release caused by the effects of negative energy on their skin. Hunduns are tireless antagonists of archons, asuras, axiomites, devils, inevitables, kytons, and other exemplars of law. They oppose any effort to impose or maintain discipline, structure, or regulation. They loathe and undermine the prospect of peace or tranquility, and relish confusion, disorder, and destruction. Though these attitudes would seem to make them ideological allies of the proteans, hunduns hold those creatures in contempt, caring nothing for that race’s strange religion, nor the spontaneous, ephemeral acts of creation in which proteans delight. Hunduns believe that the freedom and truth of pure entropy are preferable to the artificial illusions of structure, and they seek to spread this brand of enlightenment to others as part of their goal to free all creation from order’s fetters. Hunduns appear as gigantic humanoids with faces hidden by voluminous, hooded robes made out of their own wrinkled skin. In truth, their faces are not hidden, for they are faceless; the interiors of their hoods are just filled with more folds of skin. They carry staff-like objects known as strange attractors, which appear as different things to different observers but always as something that causes some form of revulsion or nausea: a shaft of knotted intestines and vital organs, studded with colored, weeping eyes; a polished metallic rod on which distorted ref lections of the observer indulge in extreme self-harm; a column of darkness in which worlds spiral toward a black heart that snuffs out the life on them. These implements are not artificial objects, but part of a hundun’s body. As well as being weapons and snares, they are methods of reproduction. Two hunduns can bring their strange attractors together, causing them to merge into an egg-shaped object under the control of one of the parents; the other parent must create a new strange attractor. This ovoid is still a strange attractor in all respects save for its shape, but if it is moved, the development of the embryonic hundun within must begin anew. The gestation of the new hundun takes many years. When the egg hatches, the strange attractor is destroyed and a fully formed hundun emerges. Reproduction between hunduns doesn’t involve any sort of love or even affection. Rather, the two hunduns feel a premonition that another hundun will be needed to fight order in the future, then meet and breed wordlessly. Hunduns can be found floating in the Negative Energy Plane or within stable voids in the planes of chaos, meditating on ways to corrupt universal truths and undermine the laws of nature on a cosmic scale—anything they can exploit to trigger the collapse and implosion of entire dimensions or planes of existence. Though they spend the majority of their time in solitary contemplation or action, hunduns sometimes gather to oppose forms of creation or manifestations of law that require greater numbers to counteract. The creatures come together spontaneously, drawn by an innate sensitivity to the structuring forces that operate on reality. Hunduns stand around 10 feet tall, yet weigh only about 700 pounds. Sustained entirely by negative energy, hunduns never eat or rest and are immune to aging; they are effectively immortal and die only through violence.

CR 21 XP 409,600 

 CE Large aberration (chaotic, extraplanar) 

     An Aberration has a bizarre anatomy, strange abilities, an alien mindset, or any combination of the three. They possess the following traits:
   • Proficient with its natural weapons. If generally humanoid in form, proficient with all simple weapons and any weapon it is described as using.
   • Proficient with whatever type of armor (light, medium, or heavy) it is described as wearing, as well as all lighter types. Aberrations not indicated as wearing armor are not proficient with armor. Aberrations are proficient with shields if they are proficient with any form of armor.
   • Aberrations breathe, eat, and sleep.

     The Chaotic subtype is usually applied to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature had a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned.

     The Extraplanar subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a Transitive Plane (the Astral Plane, the Ethereal Plane, or the Plane of Shadow).

 Init +10; Senses blindsense 300 ft., detect law; Perception +36

     Using extraordinary nonvisual senses, such as acute smell or hearing, a creature with blindsense notices things it cannot see. The creature usually does not need to make Perception checks to pinpoint the location of a creature within range of its blindsense ability, provided that it has line of effect to that creature. Any opponent the creature cannot see still has total concealment against the creature with blindsense, and the creature still has the normal miss chance when attacking foes that have concealment. Visibility still affects the movement of a creature with blindsense. A creature with blindsense is still denied its Dexterity bonus to Armor Class against attacks from creatures it cannot see.

 Negative Energy Affinity (Ex) This creature is alive but is healed by negative energy and harmed by positive energy, as if it were an undead creature.

     A creature with DR ignores damage from most weapons and natural attacks. Wounds heal immediately, or the weapon bounces off harmlessly (in either case, the opponent knows the attack was ineffective). The creature takes normal damage from energy attacks (even nonmagical ones), spells, spell-like abilities, and supernatural abilities. A certain kind of weapon can sometimes damage the creature normally, as noted below. 
     The entry indicates the amount of damage ignored and the type of weapon that negates the ability. 
     Some monsters are vulnerable to piercing, bludgeoning, or slashing damage. Others are vulnerable to certain materials, such as adamantine, alchemical silver, or cold-forged iron. Attacks from weapons that are not of the correct type or made of the correct material have their damage reduced, although a high enhancement bonus can overcome some forms of damage reduction. 
     Some monsters are vulnerable to magic weapons. Any weapon with at least a +1 magical enhancement bonus on attack and damage rolls overcomes the damage reduction of these monsters. Such creatures’ natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction. 
     A few very powerful monsters are vulnerable only to epic weapons—that is, magic weapons with at least a +6 enhancement bonus. Such creatures’ natural weapons are also treated as epic weapons for the purpose of overcoming damage reduction. 
     Some monsters are vulnerable to good-, evil-, chaotically, or lawfully aligned weapons. When a cleric or inquisitor casts align weapon, affected weapons might gain one or more of these properties, and certain magic weapons have these properties as well. A creature with an alignment subtype (chaotic, evil, good, or lawful) can overcome this type of damage reduction with its natural weapons and weapons it wields as if the weapons or natural weapons had an alignment (or alignments) that matched the subtype(s) of the creature. 
     When a damage reduction entry has a — after the slash, no weapon negates the damage reduction. 
     A few creatures are harmed by more than one kind of weapon. A weapon that inflicts damage of either type overcomes this damage reduction. 
     A few other creatures require combinations of different types of attacks to overcome their damage reduction, and a weapon must be both types to overcome this type of damage reduction. A weapon that is only one type is still subject to damage reduction.

     A creature with immunities takes no damage from listed sources. Immunities can also apply to afflictions, conditions, spells (based on school, level, or save type), and other effects. A creature that is immune does not suffer from these effects, or any secondary effects that are triggered due to an immune effect.

     A creature with resistance to energy ignores some damage of a certain type per attack, but it does not have total immunity. Each resistance ability is defined by what energy type it resists and how many points of damage are resisted. It doesn’t matter whether the damage has a mundane or magical source. When resistance completely negates the damage from an energy attack, the attack does not disrupt spellcasting. This resistance does not stack with the resistance that a spell might provide.

     A creature with Spell Resistance has the extraordinary ability to avoid the effects of spells and spell-like abilities that directly affect it. To determine if a spell or spell-like ability works against a creature with spell resistance, the caster must make a caster level check (1d20 + caster level). If the result equals or exceeds the creature’s spell resistance, the spell works normally, although the creature is still allowed a saving throw.

It is possible to address multiple creatures at once telepathically, although maintaining a telepathic conversation with more than one creature at a time is just as difficult as simultaneously speaking and listening to multiple people at the same time.

 SQ faceless, no breath 

 No Breath (Ex) This monster does not breathe, and is immune to effects that require breathing (such as inhaled poison). This does not give immunity to cloud or gas attacks that do not require breathing.

 ECOLOGY 

 Environment any (Abyss, Maelstrom, or Negative Energy Plane) 

 Organization solitary, pair, or mob (3–5) 

 Treasure none 

 SPECIAL ABILITIES

 Entropic Mind (Ex) A hundun’s mind is a maelstrom of utter chaos. A hundun is immune to mind-affecting effects, and any creature that attempts to affect a hundun with a mind-affecting effect gains 1d4 temporary negative levels (Will DC 31 negates) from entropic feedback. These negative levels disappear automatically after 8 hours. The save DC is Charisma-based.

 Faceless (Ex) A hundun has no eyes, but detects infinitesimal gravitic distortions through its skin, gaining blindsense 300 feet. A hundun is blind and deaf, and is immune to effects that depend on sight or hearing. It subsists on negative energy and doesn’t breathe, eat, or drink.

 Spacetime Shifting (Ex) Reality constantly reconfigures in the vicinity of a hundun, correcting the paradoxes the creature’s existence in space and time generates. This causes all attacks against the hundun to suffer a 20% miss chance, and grants the hundun a deflection bonus to AC and a racial bonus on Reflex saves equal to its Charisma modifier.

 Strange Attractor (Sp) A hundun can activate or deactivate the stafflike strange attractor it carries as a free action. While active, a strange attractor hovers in place, and the hundun can mentally move it up to 60 feet through space as a move action, to a maximum range of 300 feet. If it enters a space with a creature, it stops moving for the round and that creature must attempt a DC 31 Will saving throw. The creature falls unconscious for 1 round if it fails this save, or is nauseated for 1 round if it succeeds. The space around an active strange attractor twists and warps, trapping creatures within its gravity well. This functions like repulsion but in reverse: creatures within 60 feet attempting to move away from it are prevented from doing so, wasting their move actions (Reflex DC 31 negates). Lawful creatures beginning their turn within 60 feet of an active strange attractor are nauseated for 1 round (Will DC 31 negates). Nausea caused by a strange attractor is a mind-affecting effect. Creatures with the chaotic subtype are immune to all effects of the strange attractor. The save DCs are Charisma-based.  A strange attractor can’t be attacked or harmed by physical attacks, but disintegrate, mage’s disjunction, a sphere of annihilation, or a rod of cancellation affect it. A strange attractor’s touch AC is 18 (+8 deflection), and attacks against it suffer a 20% miss chance. If a hundun’s strange attractor is destroyed, the hundun can create a new one after 1d8 hours of uninterrupted meditation. If a hundun is slain, its strange attractor disappears.

 Unarmed Strikes (Ex) A hundun’s unarmed strikes deal 4d8 points of damage, and function as chaotic, magic, and adamantine weapons for the purpose of overcoming damage reduction. A hundun can make a flurry of blows attack with its unarmed strikes as a 20th-level monk, without increasing its base attack bonus or taking the –2 penalty on attack rolls.    This ability also grants the hundun the befuddling strike rogue talent and the punishing kick hungry ghost monk class feature.
