Exorcism

Ritualistic Purification. You perform a religious ceremony that beseeches a deity to aid in the expelling of a hostile spiritual presence from within a sphere 30 ft in diameter. The area of desired effect must be encircled by a ring of bone dust, and the circle must remain unbroken during the entire duration of the casting process or the spell fails. Upon successful casting, all possessing influences are annihilated within the affected area.
