This spell temporarily disrupts the loathsome forces that drive the undead ever onward, rendering them temporarily vulnerable to the cleansing power of divine magic. The targeted undead creature suffers a -1 sacred penalty to all saving throws and a -3 sacred penalty to its turn resistance. This spell affects only undead with at least 3 fewer HD than the caster has levels (i.e. a fourth level caster would be needed to affect a 1HD undead).

Focus: a scrap of clothing from any undead creature Casting this spell requires a powers check. This spell is usually cast for altruistic purposes however, halving the chance of failure.
