Necromantic

Spells of the necromantic sphere deal with the forces of life and death. These spells restore to a creature some element of its life-force that has been totally destroyed. It might be life, a limb, or an experience level. These spells are also quite useful in dealing with undead monsters. These spells in reverse are powerfully destructive, and are used only by extremely evil priests.

Note: The necromantic sphere 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.
