Necromancy is the school of magic whose spells manipulate the power of death, unlife, and the life force. Spells involving the undead make up a large portion of this school, including animate dead and finger of death.[1] Highly focused on the Negative Energy Plane, most spells from this school drain abilities.[citation needed] This school is the one most associated with lichdom, a process that allows the caster to live (or rather, exist) indefinitely by securing their essence in a receptacle known as a phylactery.[citation needed] A wizard who specializes in the necromantic school is called a necromancer.[2]
