Soul Harvest (Skill)

Soul Harvest is a Terror Witch Doctor skill in Diablo III.

In-game
When cast, leeches life force from all enemies around the Witch Doctor, causing no damage, but for every enemy harvested, the Witch Doctor will gain a bonus to total Intelligence, stacking up to 5 times (can harvest more than 5 enemies, but only 5 will give the Intelligence buff).

If cast again, the new stacks will be added to existing ones (up to the maximum limit allowed), and duration of all stacks will be refreshed. The amount of enemies to harvest is not limited.

Casting Soul Harvest does not interrupt other casts, and can be done while moving.

Runes
