Healing
From Ardrana
Spells from the healing sphere cure diseases, remove afflictions, or heal wounds. They cannot restore life or regrow lost limbs. Healing spells can be reversed to cause injury, but such use is restricted to evil priests.
Note: Healing as described here originally appeared in The Complete Priest's Handbook for Advanced Dungeons & Dragons from TSR. Its use here is for the purposes of providing context for the campaign only.
