The upside down cross item in The Binding of Isaac is called the “Black Candle.” When you enter a Devil Room, you will notice a white inverted cross appearing above Isaac’s head. This cross is a visual indicator that you have encountered the Black Candle item.
The Black Candle has a unique effect when picked up. It removes the curse from the current floor, if there is one. Curses are special conditions that can be applied to a floor, making it more challenging for the player. These curses can include things like reduced visibility, increased enemy difficulty, or limited access to certain rooms.
By picking up the Black Candle, you will no longer have to deal with the negative effects of the curse on the current floor. This can be a significant advantage, especially if the curse was making the current level particularly difficult or frustrating.
In addition to removing curses, the Black Candle also provides other benefits. It increases your overall damage and grants you a black heart, which acts as a temporary shield against damage. The increased damage can be a game-changer, allowing you to defeat enemies more easily and progress further in the game.
However, it’s important to note that picking up the Black Candle from the Devil Room will cause the white inverted cross icon to disappear. This means that if there are any other items or consumables in the Devil Room that you wish to acquire, you should do so before taking the Black Candle. Once you take the item, the Devil Room will no longer be accessible for that particular floor.
Personally, I find the Black Candle to be a valuable item in The Binding of Isaac. It can provide much-needed relief from curses that were making the game more challenging than usual. The increased damage and black heart are also great bonuses that can greatly improve your chances of success.
To summarize, the upside down cross item, the Black Candle, removes curses from the current floor and provides increased damage and a black heart. It is a valuable item that can make the game easier and more enjoyable. Just remember to take any other desired items or consumables from the Devil Room before picking up the Black Candle.
