Duality is an unlockable passive item in The Binding of Isaac, added in the Afterbirth+ DLC.
Causes both a Devil and Angel Room to spawn whenever one would spawn normally after defeating a boss.
Only one of the rooms can be entered, causing the other one to disappear.
Both rooms will spawn, even if a Devil Deal has been taken before.
Sometimes only one room will spawn if the boss room does not have enough space for both.
