You cause the target undead to approach within 5-ft. of you. If the undead is hostile, it attacks you or any other creature in range. If in order to reach you the undead would be harmed (such as fire, a pool of holy water, an enemy creature's square, etc.), the spell ends. Any attack upon the undead ends the spell immediately. A turn or rebuke attempt on the undead counts as an attack and breaks the spell. Material Component: A carved U-shaped bone.
