Hoar's Revenance

:Named Revenance in Powers & Pantheons. Renamed to Hoar's Revenance in Priest's Spell Compendium

When cast on the corpse of any sentient being killed by another sentient being, whether the death was accidental or deliberate, this spell causes the corpse to rise as a revenant, as detailed in the MONSTROUS MANUAL tome, and to immediately seek out its killer. If the corpse's killer is already dead, this spell is has no effect and is wasted. There are no ability score requirements for the dead character as there are for naturally -occurring revenants, but a salvageable corpse (at least in good enough shape to transform into a skeleton or zombie if an animate dead spell were used) must exist for this spell to be cast on. The priest has no control over the revenant and may even be attacked by the undead creature if she or he interferes in its quest for revenge. The revenant tracks its killer until it destroys the killer or until 3– 6 months pass, at which time its body disintegrates and its spirit rests in peace.

The material component for this spell is the priest's holy symbol and some token that was important to the deceased being (such as a favored scarf, locket, etc.).
