Vault is a room in The Binding of Isaac.

The Vault requires 2 keys to open and typically contains a variety of random pickups and/or chests.

It can only spawn on the second floor of a chapter, or the first floor if on the alternate path.

There is a 1/3 chance for a Vault to generate if Isaac has 2 or more keys when entering the floor. The chance increases to 4/10 if Isaac has 5¢ or more.

The Vault is mutually exclusive with the Arcade - both cannot appear on the same floor.
