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 doors are removed, allowing them to be entered and exited without taking damage.
    • Retracts damaging spikes from Spiked Rocks and Spiked/Mimic Chests.
    • Removes the spikes from Pokies, Slides, and 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 Grudges, neither retracting their spikes nor despawning them.
    • Causes Spikeballs to despawn.
      • Doesn't despawn or retract the spikes on Ball and Chains.
      • Doesn't cause the moveable spike balls in 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 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 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 or 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.
