You point your finger and fire a black ray of negative energy that suppresses the life force of any living Creature it strikes. You must make a ranged touch attack to hit. If you hit, the subject gains 1d4 temporary negative levels (see Special Abilities). Negative levels stack.

Assuming the subject survives, it regains lost levels after a number of hours equal to your Caster Level (maximum 15 hours). Usually, negative levels have a chance of becoming permanent, but the negative levels from Enervation don't last long enough to do so.

An Undead Creature struck by the ray gains 1d4 × 5 temporary Hit Points for 1 hour.
