Added in Repentance

The Mausoleum is the alternative floor to the Depths Depths and was added in The Binding of Isaac: Repentance.

Mausoleum is an occult-themed stage. Unique features of this stage include Teleporters and Grudges.

The door to the Mausoleum will appear after defeating the boss in Mines Mines II / Ashpit Ashpit II or Depths Depths / Necropolis Necropolis I / Dank Depths Dank Depths I. It costs two full hearts to enter. The damage taken ignores almost every form of damage reduction, including 15►The Wafer The Wafer and invincibility. Unlike other methods of health donation, red hearts will not be prioritized over more valuable hearts.

The door to Mausoleum II will not appear after defeating Mom.

  • While Isaac can access Mausoleum II from the Depths Depths II by unlocking the strange door, no Bosses are present on the floor when accessing it this way, so Isaac still cannot go to Corpse Corpse. Instead, the Boss Room contains 15►Dad's Note Dad's Note, which initiates the Ascent.
    • If your goal is to defeat Mother, you must use the door to Mausoleum after defeating the boss in Mines Mines II, avoiding the trapdoor to Depths Depths II.

Isaac can find both Mom and Mom's Heart in Mausoleum II; however, they are both tougher and harder than their counterparts in Depths Depths II / Womb Womb II.

  • Mausoleum Mom can be found in the boss room as usual. After that is defeated, a trapdoor and a sealed red flesh door both appear. The trapdoor only leads Isaac to Womb Womb II for now, while the red flesh door requires both 15►Knife Piece 1 Knife Piece 1 and 15►Knife Piece 2 Knife Piece 2 to be stabbed into the slot.
    • A 15►Sharp Key Sharp Key can be used in place of the Knife.
    • 15►Cracked Orb Cracked Orb's effect can open the flesh door, allowing to keep the Knife.
    • If Isaac exits the Boss Rush room after 25 minutes have passed, there is a chance that the flesh door will change positions to the wall where the boss rush door was, causing Isaac to "come out" of the flesh door and leaving it open, allowing entry without the knife.
  • After unlocking the red flesh door, the following room contains Mausoleum Mom's Heart, and once that is defeated, go back to Mausoleum Mom's room, and the trapdoor will instead lead Isaac to Corpse Corpse.
    • After defeating Mausoleum Mom's Heart, even if Isaac teleports out, all pedestal items and pickups are removed from the floor.

If the floor is exited without killing the Mausoleum version of Mom's Heart, the player will go to Womb Womb II.

The alternative floor to Mausoleum is Gehenna Gehenna. It is unlocked after all bosses from this floor have been defeated.

Trivia[]

  • In Antibirth, fully constructing The Knife required 3 Knife Pieces, with the third appearing in Mausoleum II. For Repentance, however, the third piece was removed, and the completed knife only requires the player to obtain two pieces from Downpour and Mines.
    • Also in Antibirth, there was a mechanic where somewhere on the floor, there was a special Teleporter that usually required solving a puzzle, having flight, or using pickups to access. This Teleporter led to a second section of the floor, a cluster of rooms with enemies and a few random special rooms. Since this second area was on the same map as the main part of the floor, it could also be accessed by using the Red Key enough times to reach it, or by teleporting to it with other means. Both floors of the Mausoleum had this feature, and in Mausoleum II it was required to go there to solve a puzzle in order to unlock Knife Piece 3. However, like Knife Piece 3, this mechanic was also removed in Repentance.
  • The Visage was originally a Mausoleum boss in Antibirth, but it was changed in Repentance to appear on Mausoleum's alternate floor, Gehenna. Its appearance was also updated from purple to red to reflect this.
    • This might have been because of Gehenna's "torture chamber" theming, which Visage complements more so than Mausoleum's occult theming.
  • Mausoleum is referred to on Isaac's Last Will as "Some Cursed Place".
