Upon casting of this spell, a crackling black ray of magic strikes a single target. The target immediately suffers enough negative energy damage to drain him of 1/2 of his current hit points. A creature with 1 or fewer hit points is unaffected.

If the target succeeds at a Fortitude save, he loses only 1/4 of his current hit points.

Undead, constructs, and elementals are unaffected by this spell.
