Soul Drain (Su): Each hit by one of its claws deals 1d6 points of temporary Wisdom damage to a foe. A creature reduced to Wisdom 0 by a soul eater dies. A creature slain by a soul eater cannot be returned to life by any means.

Find Target (Sp): When ordered to locate and slay a being, a soul eater does so unerringly, as though guided by discern location. The caster must know the designated creature.

Empathic Link (Ex): When summoned, the soul eater creates a mental link between itself and the caster who summoned it. Should the soul eater's victim be slain by another, or should the soul eater be defeated (not slain), it will return to the caster and attack. The soul eater can find the caster as long as they are on the same plane of existence. Should the caster leave the plane, it will temporarily break the link, though it will be reestablished once the caster returns to the same plane as the soul eater.

Immunities: Immune to poison, sleep, paralysis, and stunning. Not subject to critical hits.

*The soul eater gains a +10 racial bonus on all Hide checks when in darkness or smoke.
