'''Soul Harvest''' is a Terror [[Witch Doctor skill]] unlocked at [[clvl|level]] 9. This skill has was initially a damaging attack, but changed a great deal greatly during development, and . It is now a buff that boosts provides a considerable boost to the Witch Doctor's spell damage .  To use Soul Harvest, the Witch Doctor casts the skill and receives a stacking bonus, from 1-5, depending how many many enemies are near the WD when there are numerous he casts the spell. The radius of effect is not specified in the tool tip, but seems to be about 15 [[yards]] from the Witch Doctor. The bonus lasts for 30 seconds ([[Soul to Waste]] can double that to 60), and it can not be recast for 15 seconds. There is strategy required to use it properly, as the Witch Doctor wants to have at least four or five enemies in range when he uses the skill. Casting this with no monsters nearby grants zero bonus, and with the cooldown the vicinityskill can not be recast for 15 seconds.
