Once your Witch Doctor reaches level 70 (perhaps with a help of a leveling Build), you will be in a prime position to pick and work towards your Build. Keep in mind that your Build will not only define your gameplay going forward, but also your optimal armor and weapons.
Below you can find some of the best Witch Doctor builds for Diablo III.
Zuni Poison Dart
A ranged build that gives you an army of pets and specializes in high single-target damage. It requires paying attention to the position of your pets. Damage from this build will primarily rely on Poison Darts, which will be casted by your Fetish Army.
Mundunugu Spirit Barrage
A highly complicated, but tanky build; it has the potential for massive AoE damage. Damage from this build will primarily rely on Spirit Barrage.
Helltooth Zombie Bears
A powerful area damage Build that lets you literally run down enemies with your own swarm of bears! Damage dealt by this build will primarily rely on Zombie Charger.
