Deep dungeon

Deep dungeon or Endless dungeon are ever-changing dungeons whose architectures are never quite the same each time players enter to explore their depths. All players will begin at level one, and only by fighting the enemies within will they be able to gain the strength and experience needed to reach the final floor.

Palace of the Dead

Palace of the Dead is the first deep dungeon released in patch 3.35. Located in the The Black Shroud, Palace of the Dead features 200 Floors.
