Mind Feed (Ex): A phthisic that hits with its bite attack deals 1d4 points of temporary Intelligence damage. If this reduces the opponent's Intelligence score to 0, the damage becomes permanent.
Regeneration (Ex): Fire and acid deal normal damage to a phthisic.
Psionics (Sp): At will - brain lock, dimension slide, and skate. These abilities are as the powers manifested by a 15th-level psion.

Born of a damaged mind, a phthisic constantly craves the sweet nectar of sanity to sooth its mental torment, if only for a while. As it feeds on a living being's Intelligence, the victim experiences a sensation of deadly chill.
