Charm Spirit

This spell allows the caster to charm any specified spirit within range. The caster must be able to see or otherwise know the location of the spirit. The spirit might be bound into an object; possessing a person, animal or object: or free. The spell cannot be used to charm spirits that are naturally bound, such as nature spirits.

If the chosen spirit fails to roll a successful saving throw vs. spell, then it obeys the caster as a faithful servant for the duration of the spell, even attacking its own allies. However, no spirit can be forced to perform actions against its own alignment.

The material component is a crystal ball, worth at least 50 gp.
