Cure Undead

A 50 ft sphere of holy light surrounds the caster's body. Any undead caught in this sphere reverts to the form it took before it was cursed, but only as a corpse. Once it is no longer undead, it can't become undead again for 1 year. The spell does nothing when cast on sentient undead (Acererak for example) or a non-animated corpse.

At higher levels: When the spell is cast using a 9th level spell slot, the target is revived as if it were brought back with a True Ressurection spell, and can never become undead again.
