  This spell functions as rage, except it affects only undead creatures and bolsters them with necromantic energy rather than emotion. Each affected creature gains a +2 Profane Bonus to Strength and Charisma, a +1 Profane Bonus on Will saves, and a -2 penalty to AC. The effect is otherwise identical to a barbarian's rage.
