Witch Doctor

Zharvakko the Witch Doctor is a ranged intelligence Hero who can take on the role of a support or a ganker. A master of voodoo curses and healing arts, he possesses several positioning-dependant crowd control/damage spells as well as a heal that scales well into the late game. Malediction is one of the most powerful damaging spells in the game, and is fittingly enough quite hard to hit properly - but when applied at the right time, Malediction can curse someone to suffer a slow, humiliating death as they limp back towards safety.
