Chattel Spirit

Any nemesis spirit that the caster has defeated can be summoned with this spell. It appears with whatever powers and hit points it had when the barbarian cleric fought it. It must serve the caster or answer the caster's questions to the best of its ability. When the spell ends, the spirit vanishes, even if its task is incomplete. Although the spirit may complain or attempt to bend the meaning of a command, it is bound to carry out orders, even if these could result in the spirit's destruction. Once slain in an assignment, a spirit cannot be called on again. Only three services can be asked of any individual nemesis spirit.

The material components are 100 gp of very rare herbs, which are burned as the caster performs a chant, dances, and gestures with a holy symbol.
