Feeding (Su): A warp drifter can attach itself to an immobilized living creature (such as a victim that has lost all it Dexterity to the warp drifter's spore attack) and feed off its life force. The victim takes 1 point of temporary Constitution damage for each hour the drifter stays attached. If the drifter remains attached for a full 24 hours, the victim dies no matter what its current Constitution score.

Levitation Field (Su): Creatures of the same size or smaller than the warp drifter within a 15-foot radius of the drifter are raised 20 feet into the air as though affected by a levitate effect. A successful DC 16 Reflex save protects a creature from the effect for 1 round. Creatures that fail the save remain levitated until they move away from the warp drifter. The save DC is Dexterity-based.

Poison Spores (Ex): Creatures in the levitation field are exposed to poisonous spores each round. Injury, Fortitude DC 16, initial and secondary damage 1d4 Dexterity. The save DC is Constitution-based. Psionic targets with power points lose 1d4 power points instead of taking Dexterity damage; if a psionic creature has no power points to lose, it takes Dexterity damage instead.

Psi-Like Abilities: At will -- chameleon, mind thrust (5d10, DC 10*), telekinetic force (300 pounds, DC 10), thicken skin (+2 enhancement bonus to AC*), vigor (25 hp*). Manifester level 5th. The save DCs are Charisma-based.

*Includes augmentation for warp drifter's manifester level.

Tree Shape (Sp): A warp drifter can change its appearance at will. It can take on the appearance of a nearby tree and surrounding foliage. Changing to or from tree shape is a full-round action.

Warp drifters disguise themselves as common trees, and they attack by levitating opponents. They manifest mind thrust for protection, and creatures caught in their levitation field are exposed to poisonous spores. They often use telekinetic force to force creatures into their levitation field.
