Necromancer

Often found near Temples of Darkness and in unholy swamps, Necromancers raise the dead to do their bidding for them. And, more importantly: to distract defenses from attacking them. They also have the ability to cast a powerful dark Death Coil spell, which damages the living. Necromancers are somewhat frail themselves, however, and taking them down tends to stop the onslaught of the walking dead.
