Unlock Method	Blow up doors and Secret Room walls 50 times

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

Effects

• 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 door will still close upon opening a chest.

Notes

• Does not work on Secret Room openings.
• Does not work on Greed Mode.
• This allows Isaac to leave rooms, including boss rooms, if the fight goes poorly.
  • This becomes particularly useful in 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 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 has a Krampus fight in it, Isaac may choose not to fight him and leave.
• If an Angel fight is started in an Angel Room the door will close and prevent leaving despite the Door Stop.
• If Greed spawns in a Secret Room or Shop, Door Stop can be used to leave and come back to fight Greed again to potentially get more than one Steam Sale.
• Does not affect Mom's boss room.
• Can be used to reset Holy Mantle shield. Very useful playing as The Lost.
• 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 after the fight has started.
• Cannot be used to escape the Mega Satan fight.
• Extremely useful with Tainted Keeper, as it can be used to reset a room and farm coins. Enemies keep the same value of coin they drop, so if an enemy drops a dime that enemy will always drop a dime.
