Wilken's Reach is a Legendary mojo that was introduced in patch 2.4 of Diablo III. It requires character level 70 to drop. The unique affix removes the Grasp of the Dead cooldown, making only Mana cost limit its casts. If coupled with Unbreakable Grasp, it will also remove the Mana cost. Desperate Grasp rune, however, becomes useless with this item. Remember that most effects of Grasp of the Dead do not stack if the spell is cast multiple times in the same area. Rain of Corpses is a notable exception. This item makes Zunimassa's Haunt Set Dungeon considerably easier to beat.
