Binding of Isaac: Rebirth Wiki

Added in Repentance

Flat File is a trinket added in The Binding of Isaac: Repentance.


  • Makes all spikes retract, preventing them from dealing damage.
    • Most spikes leave behind holes or a visual cue showing where they would normally be.
    • The spikes around Curse Room Curse Room doors are removed, allowing them to be entered and exited without taking damage.
    • Retracts damaging spikes from Spiked Rocks and Spiked Chest Spiked Chests/ Mimic Chest Mimic Chests.
    • Removes the spikes from Poky Pokies, Slide Slides, and Wall Hugger Wall Huggers.
      • Pokies, Slides, and Wall Huggers don't immediately stop moving once they are despiked, and are still able to push Isaac without dealing damage.
      • Has no effect on Grudge Grudges, neither retracting their spikes nor despawning them.
    • Causes Spikeball Spikeballs to despawn.
      • Doesn't despawn or retract the spikes on Ball and Chain Ball and Chains.
      • Doesn't cause the moveable spike balls in Singe Singe's boss room to despawn or despike.


  • If Flat File is dropped in a room with spikes, the spikes will not extend again unless the room is left and re-entered.
    • Spiked Rocks will not re-extend their spikes.
  • Mimic Chest Mimic Chests won't change their contents when Isaac is up close to them (visible with Guppy's Eye Guppy's Eye) if opened under the effect of Flat File.
  • Flat File also retracts the spikes in the center of Sacrifice Room Sacrifice Rooms, making them unusable while the trinket is held. The spikes reappear after dropping the trinket and re-entering the room.
  • Flat File does not prevent The Pile The Pile or Mama Gurdy Mama Gurdy from using their spike attacks.
  • Also removes spikes from doors in the Cursed! challenge, making it much easier.

  • The Flat File assumedly "files" down the spikes, like one would file the jagged imperfections from their nails, or file metal bars to escape from jail.
