Proteans

Outsider: An outsider is at least partially composed of the essence (but not necessarily the material) of some plane other than the Material Plane.

Outsiders have darkvision.

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. A different magical effect, such as limited wish, wish, miracle, or true resurrection, is required to restore it to life. An outsider with the native subtype can be raised, reincarnated, or resurrected just as other living creatures can be.

Outsiders breathe, but do not need to eat or sleep (although they can do so if they wish). Native outsiders breathe, eat, and sleep.

Chaotic: Chaotic creatures are usually outsiders native to the chaotic-aligned Outer Planes. Most chaotic creatures also have chaotic alignments; however, if their alignments change, they still remain chaotic creatures. Any effect that depends on alignment affects a chaotic creature 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 chaotic creature overcomes damage reduction as if its natural weapons and any weapons it wields are chaotically aligned.

Extraplanar: Extraplanar is 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. Creatures not 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, such as the Astral Plane, the Ethereal Plane, or the Plane of Shadow.

Protean: Proteans are serpentine outsiders of pure chaos.

They have blindsense.

Proteans have immunity to acid.

They have resistance to electricity and sonic.

Proteans can constrict and grab.

They have supernatural flight.

A protean has continuous freedom of movement, as per the spell.

A protean’s vital organs shift and change shape and position constantly. This grants it a chance to ignore additional damage caused by critical hits and sneak attacks, and grants it immunity to polymorph effects (unless the protean is a willing target). A protean automatically recovers from physical blindness or deafness by growing new sensory organs to replace those that were compromised.

A protean’s form is not fixed. Once per day, a protean may change shape into any Small, Medium, or Large animal, elemental, giant, humanoid, magical beast, monstrous humanoid, ooze, plant, or vermin. A protean can resume its true form, and when it does so, it gains the effects of a heal spell.

Shapechanger: A shapechanger has the supernatural ability to assume one or more alternate forms. Many magical effects allow some kind of shapeshifting, and not every creature that can change its shape is a shapechanger.

Beings of pure chaos, the serpentine proteans slither through the anarchic improbabilities of Limbo, remaking reality according to their whims. According to their own history, they were already here when the first gods pulled forth the other planes from raw chaos — and they have been battling against the indignity ever since. Hereditary and ideological enemies of Axis, Heaven, and Hell, and especially of the residents of those planes, all proteans see it as their sacred duty to return the bland, static expanses of mundane reality to the beautiful incongruities of Limbo, for the planes’ own good and for the greater glory of their mysterious god, a dualistic deity which may be a living aspect of Limbo itself. They are Limbo’s living, breathing immune system, rooting out infections of mundanity and replacing them with beautiful entropy.

Primeval in shape and philosophy, proteans are the race that most perfectly embodies the twin aspects of creation and destruction (although certain aeons might contest this claim). Even their language is mutable, evolving so quickly that few outsiders can understand it without magical aid. Ecological study is nearly impossible, as reproduction can take a wide variety of forms, from sexual union to fission to spontaneous generation. Despite their deceptively similar natural appearances, the two things that truly unify the protean race are slavish devotion to their strange god and a fervent desire for the dissolution of reality as we know it.

Proteans are organized into several sub-races or castes, each with its own individual abilities and roles. Other proteans doubtless exist, but they do not interact with other races.

Voidworms: Disowned by greater proteans, who find these tiny beings shameful, voidworms nevertheless retain all the characteristics of true proteans, and are frequently found swimming through Limbo in vast schools or serving as spellcasters’ familiars.

Naunet

Far more bestial than their kin, naunets are the lowest caste of the true proteans, the shock troops of their race and roving marauders in the cause of chaos. Primarily found in the shifting borderlands between Limbo and other planes, naunets are driven half-insane by the stability and stasis of such areas, and frequently rampage through the edges of other planes, tearing up the very fabric of reality itself and returning vast swaths of land to the beautiful, formless potentiality of their home.

Naunets have spell-like abilities.

A naunet’s natural weapons count as magical and chaotic for the purposes of overcoming damage reduction. A naunet may infuse all of its natural attacks with adamantine, silver, or cold iron, thereby allowing it to overcome damage reduction of those types as well.

Once per day, three or more naunets working together can create a roiling cloud of multicolored chaos matter. This effect is identical to solid fog but doesn’t last as long. If six or more naunets are present, the coalesced chaos instead functions as acid fog.

A creature struck by a naunet’s tentacle attack is infused with raw chaos, and may be confused momentarily. A creature with a chaotic component to its alignment gains a bonus on saves against this effect, and creatures with the chaotic subtype are immune. This is a mind-affecting effect.

A naunet is 12 feet long and weighs 900 pounds.

They have damage reduction that can only be bypassed by lawful weapons.

They are immune to polymorph.

They have spell resistance.

They can detect law.
