Exorcism
Description: The mage seeks to exorcise a spirit which has manifested on the physical plane. In practice, the mage is trying to throw it out in the Umbra again. Most spirits are naturally opposed to this, and will use any means necessary to prevent this. Most spirits try to sneak away on the physical plane if they can or the exorcist seems dangerous. Others attack the exorcist physically, mentally or with cunning.
System: The rite is an extended action, where each success of the mage temporarily decreases the Arete of the spirit during the exorcism. The difficulty is the Arete of the spirit +4. If it reaches zero the spirit is banished. If the mage botches the spirit can possess him if it wants to, or even banish the soul of the mage to the Umbra if it is powerful enough
