Sacred Harvester

The Sacred Harvester is a legendary ceremonial knife for the Witch Doctor in Diablo III, added in patch 2.1. It requires character level 12 to drop, and originally only dropped during the Season One for Seasonal characters. After the end of the Season One, it drops for normal characters as well.

The unique affix allows the Intelligence buff from to stack 10 times, instead of 5. It still allows old stacks to stack with the new ones. Secondary effects that scale with number of stacks also can go up to 10.
