Psionic Leech

Psionic leeches resemble their natural and magical kin except for a bluish tint to their rubbery black skin and a faint crimson glow visible in darkness. Tiny hooks line their flat bodies, catching on cloth and fur. They cannot communicate.

Psionic power is rarer than magic in the misty dread realm, so these parasites are ruthlessly efficient: each steals 1 PSP per turn from every creature no more than 1 yard away. The victim may check once per turn to notice, with a percentage chance equal to the PSPs lost. The leeches then must be found in clothing folds, cuffs, boots or armor joints, one Intelligence check and 1 round apiece.

Touching one triggers a psychic blast of 1 point per PSP it stole in the past 8 hours. Mindblank, tower of iron will and similar defenses halve both drain and blast. A psionicist with no PSPs left still attracts them, and while they try to feed he makes one madness check per round regardless of their number.

Psionic leeches have no society but cluster in groups of 5d6 (5-30) in swamps, marshes, ponds, wet grass and slow streams, and anyone crossing a nest gathers 1d6. Their hooks hold them until their host's powers are gone or better food appears.

Bloated with energy, a leech falls off, crawls to the closest wetland and births 1-6 young in 3d4 days.
