The Zombie tree focuses on creating witch doctors whose main role in battle is to have a lot more of summoned summoning various [[pet|minions than witch doctors of other builds]].

Luckily for us, the Zombie tree has a few cool skills that makes enemies easy to kill, like Sacrifice, Parasite and Wall of Zombies.
