Yuan-ti abominations are all snake (01-50 on d%) or have a single human feature, either a head (51-75) or arms (76-00).

Yuan-ti speak their own language, plus Common, Draconic, and Abyssal.

Improved Grab (Ex): To use this ability, a snake-headed abomination must hit with its bite attack. If it gets a hold, it can constrict.

Constrict (Ex): An abomination deals 1d6+6 points of damage with a successful grapple check (using the bite attack bonus if snake-headed) against Large or smaller creatures.

Spell-Like Abilities: (Human-headed) 1/day-animal trance, cause fear, deeper darkness, entangle, neutralize poison, suggestion, and polymorph other. These abilities are as the spells cast by an 8th-level sorcerer (save DC 13 + spell level).

Psionics (Sp): All yuan-ti can produce the following effects at will:

  • Detect Poison: As the spell cast by a 6th-level sorcerer.
  • Alternate Form: The yuan-ti can assume the form of a Tiny to Large viper. This ability is similar to a shapchange spell cast by a 19th-level sorcerer but allows only viper forms. If the yuan-ti has a poisonous bite of its own, it uses its own or the viper's poison, whichever is more potent.
  • Chameleon Power: The yuan-ti can change the coloration of itself and its equipment to match its surroundings.
  • Produce Acid: The yuan-ti can exude acid from its body, dealing 1d6 points of damage to anything it touches. The acid becomes inert when it leaves the yuan-ti's body.
  • Aversion: The yuan-ti creates a compulsion effect targeting one creature within 30 feet. The subject must succeed at a Will save (DC 17) or gain an aversion to snakes for 10 minutes. Affected subjects must stay at least 20 feet from any snake or yuan-ti, alive or dead; if already within 20 feet, they move away. A subject can overcome the compulsion by succeeding at another DC 17 Will save, but still suffers deep anxiety. This causes a -4 reduction to Dexterity until the effect wears off or the subject is no longer within 20 feet of a snake or yuan-ti. This ability is otherwise similar to antipathy as cast by a 16th-level sorcerer.

Poison (Ex): Halfbloods and abominations with snake heads only-bite, Fortitude save (DC 17); initial and secondary damage 1d6 temporary Constitution.

Skills: *Yuan-ti using chameleon power receive a +8 circumstance bonus to Hide checks.
