Justice Lantern is a Legendary ring in Diablo III. It requires character level 50 to drop. Unlike most rings, it is block-oriented, most useful to Crusaders. It can roll the highest crowd control reduction in game (up to 70% at level 70), potentially allowing the bearer to ignore those completely (technically, reducing them to the negligible duration). Chance to Block also may not normally roll on a ring. This ring rolls 5 Primary affixes.
