Before you begin the exorcim of the demoniac who suffers from complete diabolical possession:
She must be modestly attired; pajamas or hospital scrubs are good. Have spare attire ready. Nothing about the neck. No jewelry. She is expected to involuntarily defecate and urinate; an adult disposible diaper is suggested. Everyone who needs to be present must be present. Instruct everyone to obey the exorcist without questioning. When the energumen exhibits sexual behaviors, they are not to stare at her nude body, except to cover her immodesty.
The energumen must be properly secured in straight jacket, or hospital posey restraints and strong chains. When the Litany of the Saints commences, expect that nothing may happen, or all hell may be unleashed.
