Eat Thoughts (Su): A thought eater can drain power points with a successful melee touch attack. This ability resembles the psychic vampire power but drains 6 power points from the victim. Against a non-psionic creature, this touch attack deals 1 point of temporary Intelligence damage, which provides nourishment equivalent to 6 power points.

A thought eater requires 10 power points per day to survive but will gorge itself on weak prey.

Ethereal Jaunt (Su): A thought eater can shift from the Ethereal Plane to the Material Plane as part of any move action, and shift back again as a free action. The ability is otherwise identical to ethereal jaunt manifested by a 15th-level psion.

Psionics (Sp): At will -- detect psionics, distract, inkling, and know direction. These abilities are as the powers manifested by a 15th-level psion.

Attack/Defense Modes (Sp): At will -- none/thought shield.

Feats: Thought eaters gain Improved Initiative as a bonus feat.

A thought eater lurks on the Ethereal Plane waiting for an intelligent creature, or better yet, a psionic creature to happen by. Upon locating one, it shifts to the Material Plane, attempting to catch its victim unawares. After a successful attack, the thought eater quickly retreats to the Ethereal Plane to digest the meal.

A thought eater can spend a maximum of 10 continuous rounds on the Material Plane before its wispy flesh finally dissipates and it falls dead. If badly wounded, it escapes to the Ethereal Plane rather than continue the fight.
