A ti-khana deinonychus leaps at prey, tearing with its talons (counting as a single attack), grasping with its foreclaws, and biting with its terrible jaws adding a toxic venom to the deinonychus's already fearsome attack routine.
Poison (Ex): A ti-khana deinonychus delivers its poison (Fort DC 16 negates) with each successful bite attack. Initial and secondary damage are the same (1d6 Con).
Psionics (Sp): A ti-khana deinonychus can produce the following effects at will.
Detect Poison: As the spell cast by a 6th-level sorcerer.
Alternate Form: A ti-khana deinonychus can assume the form of a Tiny to Large viper (see the Monster Manual). The ti-khana deinonychus uses its own or the viper's poison, whichever it prefers.
Aversion: A ti-khana deinonychus creates a compulsion effect targeting one creature within 30 feet. The subject must succeed on 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, yuan-ti, or ti-khana, alive or dead; if already within 20 feet, they move away. A subject can overcome the compulsion by making another Will save (DC 17), but still suffers from deep anxiety. This anxiety causes a -4 penalty to Dexterity until the effect wears off or the subject is no longer within 20 feet of a snake, yuan-ti, or ti-khana. This ability is otherwise similar to antipathy as cast by a 16th-level sorcerer.
Scent (Ex): A ti-khana deinonychus can detect approaching enemies, sniff out hidden foes, and track by sense of smell.
Skills: A deinonychus has a +8 racial bonus on Hide, Juimp, Listen, Spot, and Survival checks. *The bonus on Survival checks increases to +12 when tracking by scent.
