This spell is much like the wizard spell of the same name. The caster affects one touched undead per level, making it immune to an initial attempt to turn, destroy, or command it by a priest, paladin, or other being with power over undead. The spell ends as it prevents that one attempt; later attempts have a normal chance of success (the spell does not protect undead from spells or magical item effects). Protected undead radiate a faint magical aura. Unlike the wizard spell, multiple priest revenances can be cast on a single undead; each turning attempt ends only one spell, leaving the others operating.
The material components of the spell are a pinch of dust for each undead creature to be affected.
Notes: Rare spell granted by drow deities in the Forgotten Realms setting.
