Spell-like Abilities: 1 day - disguise self, color spray, feather fall, ray of enfeeblement, reduce, spider climb. Caster level 2nd; save DC 14 + spell level.

Vile Transformation (Su): A kaorti can infuse any living creature with otherworldly essence from the Far Realm, permanently transforming the target into a mockery of its previous form. This process takes 8 hours, during which time the kaorti's jaws must be locked onto the victim, who must be either willing or helpless for the duration. After 8 hours, the victim must make a Fortitude save (DC 11). Failure indicates that the victim transforms into a kaorti (if the victim was a humanoid), or into a kaorti thrall. If the victim succeeds at the save, the kaorti can attempt the transformation again; each additional attempt to transform a victim increases the save DC by +1.

Creatures transformed into kaortis retain any class abilities and modify their ability scores as follows: Str -4, Dex +4, Int +4, Cha +6. They become neutral evil and embrace the racial ethos of the kaortis. They gain all of the other abilities and disadvantages of a standard kaorti. This transformation is the only way the kaorti can propagate their kind.

A victim transformed into a kaorti thrall gains the fiendish creature template, except that instead of gaining the smite good special attack, it gains the ability to cast true strike on itself once per day.

Material Vulnerability (Ex): The Material Plane is painful to an unprotected kaorti. An unprotected kaorti must make a Fortitude save each hour (DC 15, +1 per previous check) or take 1d6 points of subdual damage and become fatigued. The fatigued condition persists until the kaorti recovers all the subdual damage it took from its exposure to the Material Plane. If a kaorti is rendered unconscious through the accumulation of subdual damage (from this ability or from any other source), the Material Plane environs begin to deal normal damage at the same rate (Fort save negates; save DC continues to increase per check as stated above). A kaorti wearing a resin suit, or a kaorti inside a cyst, is protected from the effects of the Material Plane.

Outsider Traits: Kaortis have darkvision (60-foot range), and they cannot be raised or resurrected (though a wish or miracle spell can restore life).

Skills: Kaortis have a +8 racial bonus on Heal checks.

Evil Subtype

A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil 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 has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned (see Damage Reduction).

Extraplanar Subtype

A subtype 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. This book assumes 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 when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.

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 transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
