Binding of Isaac: Rebirth Wiki

Forget Me Now is an unlockable activated item.


  • On use, the current floor will be completely re-generated and Forget Me Now will be removed from Isaac's inventory.
    • Isaac will restart the level as if he had entered a new floor.


  • The re-generated floor will count as the same floor number as the one Isaac used Forget Me Now in.
    • If a Devil Room Devil Room / Angel Room Angel Room is not encountered after defeating the boss of the re-generated floor, the multiplier tied to the number of floors since the last Devil/Angel Room affecting the spawn chance will not change.
      • Added in Repentance If the first possible Devil Room Devil Room is encountered, the 100% chance for the next deal to be an angel chance is preserved upon regenerating the floor.
    • If a Devil/Angel Room is encountered before regenerating the floor, the multiplier will become x0.25 upon regenerating the floor.
  • Any items earned before using the re-generation effect will remain in Isaac's inventory.
  • If used on the Depths Depths / Necropolis Necropolis / Dank Depths Dank Depths II after beating Mom Mom, both The Negative The Negative and The Polaroid The Polaroid can be obtained in one run. Additionally, two Boss Rush Boss Rushes can be entered as long as the total playtime of the run stays under 20 minutes.
    • Added in Repentance This also allows opening the door to Mausoleum Mausoleum / Gehenna Gehenna II in the starting room.
  • Added in Repentance If used on Downpour Downpour / Dross Dross II after collecting Knife Piece 1 Knife Piece 1, a second Knife Piece 1 Knife Piece 1 will spawn in the mirrored world's Treasure Room Treasure Room, which can be rerolled into a random item from the Treasure Room (Item Pool).
  • If used on Chest Chest or Dark Room Dark Room when the door to Mega Satan Mega Satan has been opened, the golden key will not re-open the door and you will be unable to fight him.
  • If used on an XL floor, the merged chapter can be re-generated as two separate floors instead.
  • If used on Womb II/Utero II/Scarred Womb II after defeating Mom's Heart, and Mom's Heart is again defeated on the regenerated floor, it will count as having defeated Mom's Heart 2 separate times, therefore unlocking 2 consequent endings.
  • Challenge Room Challenge Rooms and Boss Challenge Room Boss Challenge Rooms will have the same rewards and enemy waves as the Challenge Room in the previous iteration of the floor.
  • Added in Repentance If left in a Treasure or Boss Room and then returned to during the Ascent, the Forget Me Now item will return to the room it was left each time it is used, allowing the floor to be repeated indefinitely.
    • This can be useful in conjunction with Added in RepentanceThe Stairway The Stairway, as it allows for unlimited Angel Shops to be visited.
    • Upon reentry, items, pickups, and trinkets left in treasure and boss room after using Forget Me Now will be removed and not converted into cracked keys.
  • If used in Floor 1, the chance of Devil/Angel room is still 0%.
  • Added in Repentance If used on Mausoleum or Gehenna II after the special version of Mom's Heart Mom's Heart is defeated, the newly generated floor will be dimly lit as though Mom's Heart was already defeated. Additionally, no items will naturally generate in rooms where they would have. After the player defeats Mom Mom again, there will be no flesh door, and the trapdoor to Corpse Corpse will appear.

Bug Bug! The new floor is improperly seeded. This results in a high chance for rooms to repeat from the previous floor. This is most noticeable when looping via the error room. This bug is due to ForgetStageSeed using the same xorshift constants as the level generator.
