Upon activation, the player grows angel wings and gains the ability to fly for that room. Using the Bible on Mom or Mom's Heart/It Lives will result in an instant kill. Using the Bible on Satan or Isaac will instantly kill the player, but with The Wafer this is reduced to half a red heart and all soul hearts. It will not kill the player if used on ???, however.
