Roguelike dungeons will be a step up in challenge, particularly on Ultimate difficulty, with two to three Mutators active. In return, the final chest of each roguelike dungeon will always attempt to drop at least two Epic quality or higher items (one guaranteed to be Legendary) on Ultimate difficulty, on top of the significantly increased Rare quality drop rates across the entire dungeon.
