[Spells help] exorcism

Syntax: cast exorcism 

Sometimes the spirits become so intrusive into the lives that they are no
longer able to lead, that the living become resentful.  By using the spell
of exorcism, a ghost is banished back to the Afterlife and is forced to
remain there for some period of time.  This spell can only be used in the
presence of the ghost, although it need not be manifested at the time.
