Door Stop

Door Stop is an unlockable trinket added in The Binding of Isaac: Afterbirth †.

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.

Trivia

 * Door Stop has been added in Booster Pack, after the initial release of the DLC.
 * Door Stop is based on this Steam Workshop trinket by Strawrat and CupertinoEffect.
