Home of Witch Doctors is the Toranjan Jungle. In Diablo II, we had a Necromancer class which is similar to the Witch Doctor but is not meant as a replacement by Blizzard. The Witch Doctors can draw power from an alternate reality they call the Unformed Land.
They can use this power to curse their enemies. In addition they can raise the dead and manipulate them in fighting for them.
