The Demon Shaft is a dungeon in Dark Cloud that is unlocked after defeating The Dark Genie. It consists of 100 floors with the boss on the 100th, and due to its nature as a bonus dungeon, it has no story and does not belong to a town. The item needed to enter the back floors is the Crystal Eye. This is also the largest dungeon in the series with 100 floors, with the Zelmite Mine's 38 floors coming in second. Floors 1-20 (Fire Zone) is the only part of the Demon Shaft not to have Mimics or King Mimics.
