==Mana Resource==

The Witch Doctor is the only class in Diablo 3 who uses [[mana]] as a character resource. In this the WD is very conventional and familiar to people who played Diablo and Diablo 2. The character casts spells that cost X amount of mana, which regenerates over time, at a rate determined by various factors including total mana pool, item modifiers, and relevant skills.
