Binding of Isaac: Rebirth Wiki

Added in Afterbirth †

Door Stop is an unlockable trinket added in The Binding of Isaac: Afterbirth † (Booster Pack #3).


  • While held, the last door Isaac went through stays open, allowing him to leave the room even if enemies are in it.
    • Does not prevent doors from closing due to other triggers, e.g. a Challenge Room Challenge Room door will still close upon opening a chest.


  • Does not work on Secret Room Secret Room openings.
  • Does not work in Greed Mode.
    • Added in Repentance Cannot spawn in Greed Mode.
  • This allows Isaac to leave rooms, including boss rooms, if the fight goes poorly.
    • This becomes particularly useful in The Void The Void, where there are multiple boss rooms; Door stop lets the player peek behind each boss room, and thus able to decide whether to face Delirium Delirium or other bosses first.
  • Leaving immediately after enemies have spawned gives the player information on the fight, potentially improving decision making.
  • If a Devil Room Devil Room has a Krampus Krampus fight in it, Isaac may choose not to fight him and leave.
  • If an Angel fight is started in an Angel Room Angel Room the door will close and prevent leaving despite the Door Stop.
  • If Greed Greed spawns in a Secret Room or Shop Shop, Door Stop can be used to leave and come back to fight Greed again to potentially get more than one Steam Sale Steam Sale.
  • Does not affect Mom Mom's boss room.
  • Can be used to reset Holy Mantle Holy Mantle shield. Very useful playing as The Lost The Lost.
  • Removed in Repentance If a room contained champion enemies, upon leaving and re-entering the room, all previous champion enemies will have turned to regular enemies.
  • Cannot be used to escape Boss Rush Boss Rush after the fight has started.
  • Cannot be used to escape the Mega Satan Mega Satan fight.
