蓝钥匙#150

This article is about the trinket that creates Blue Womb rooms. For the trinket that opens the Hush fight and empowers Pandora's Box, see Strange Key. Blue Key is an unlockable trinket added in The Binding of Isaac: Repentance.

• The trinket might be a reference to SCP-860, a fictional key that acts in a near-identical manner.
• If used on the ??? floor, one might hear the mid-combat layer of the floor's theme, Nativitate, an asset which was previously unused.

Bug! If used with The Forgotten and Birthright, leaving The Forgotten's body in the hallway will cause it to reappear next to you when you exit, but upon switching back to the body, it will become immobile, and switching back to the soul will make it immobile too, causing a softlock requiring you to exit then continue the run. Bug! Opening a locked door without entering it and then leaving and re-entering the room will no longer cause the door opened by Blue Key to lead to a Blue Womb room. In other words, this removes the downside of the trinket. Keys Items
