How to calculate the probability of opening the Devil's Room in "The Binding of Isaac"? Today, the editor brings an analysis of the probability of opening the Devil's Room. Come and learn.
First of all, the devil room and angel room are very important in the game. There will be some powerful props in the room. These two rooms are also the main way for us to obtain huge improvements in the game in the short term. These two rooms will only be on floors 2-8. The probability will be activated after clearing the boss room, but you can teleport directly into the Demon Angel room through some special means. First, let’s talk about the opening of the devil room. From the second to the eighth floor, the opening probability next to the Demon Angel will be displayed in the status bar. It is usually displayed on the second floor. Our character has a 135% opening rate of the Demon Room. The panel will only display to 100% when our character's heart is damaged by monsters or traps on this layer. It will reduce the opening rate by 99%, leaving only 36% of the opening rate. When the character is injured in the boss room, the opening rate will be reduced by 35% again. There is only one percent open rate left. Above, we classify it as the initial opening rate. Then when your Devil Room opening rate drops very low due to the injury to the red star. How to increase it again? Then there are several methods below to increase the opening rate of the object side. We classify these methods as additional opening rates.
So after we defeated the boss on the second floor. The opening rate of the middle house is the initial opening rate plus the additional opening rate. If we reach a new floor and the Devil's Room has been opened on the upper floor, all opening rates will be multiplied by 0.25. If the Devil's Room has not been opened on the upper floor and the Devil's Room has been opened on the upper floor, the opening rate will be 10.5. If the Demon Room is not opened on two consecutive floors, all opening rates will be calculated as normal.
