Exorcism

A clerical savant casts this spell to rid one object or area of an evil spirit. The casting time is equal to one turn per hit die of the spirit, during which the caster is shielded as if by a protection from evil 10' radius spell.

Each turn of casting, the savant must roll 4d6 for a total below his or her Constitution, subtracting one from the roll for each four levels of experience (round fractions down). Failure ends the spell, subjecting the savant to possible attack from the enraged spirit. If the exorcism fails, another attempt can be made 24 hours later.

At the completion of the casting time, the spirit must make a successful saving throw vs. spell or be forced back to the realm of the dead. Success means the creature is driven away, remaining in the general area but losing one-fourth of its hit points. If subsequent exorcisms reduce the spirit to zero hit points, it is permanently driven from the area. Any noncorporeal undead or restless life force can be affected, including any singular undead possessing or haunting an individual, object, hallway, room, etc. This does not include intelligent undead in the vicinity of a specific lair (vampires, liches, death knights, etc.).

The material components of the spell are a small silver bell, a book of prayers, and a blessed candle that must remain lit throughout the ceremony. Upon completion of the spell, the savant snuffs out the candle and destroys it.
