Psionic Spirit

This rare ghost uses psionics instead of magic. Always ectoplasmic, it looks like a softly shimmering human or demihuman whose limbs dissolve into wisps; stray tendrils sometimes drift off and congeal into stinking jelly. It speaks only its living languages, but psionicists can reach it telepathically.

Its disciplines: psychometabolism (devotions cause decay, aging); psychokinesis (sciences project force, telekinesis; devotions control lights, control sound, control body, animate object); telepathy (sciences probe, mind wipe, mind link; devotions contact, ESP, aversion, attraction, phobia amplification, post-hypnotic suggestion, false sensory input, psionic crush).

It lives to torment minds and loathes psionicists, wrecking first their minds, then their bodies. It softens victims with fear and confusion before striking openly, usually spreading chaos with control body and then hitting casters and psionicists with psychic crush or aging. Any successful probe can make a character of any class stare into its mad mind and roll a madness check. Only +1 or better weapons harm it, and it ignores cold, poison, hold, charm and sleep. Priests turn it as a ghost, and each vial of holy water deals 2d4.

These ghosts roam widely, hunting psionicists. Some say they are psionicists trapped in shadow form until madness drove them to the dark powers of the realm, who made them ghosts; others say they are evil psionicists who died violently mid-power.

They ignore treasure; any in a lair belonged to victims. In the misty dread realm, each use of retrospection has a 5% chance of summoning one, since they can sense it.
