how do I get angel/devil deal rooms

[Someone’s Son (she/her)]

I heard that there are 2 types of rooms that unlok if you beat a boss with the right requirements

[MediocreOmen]

You can get them from Basement II all the way to Womb II, To get it, either find the "Goat Head" item for a 100% chance for one to appear (They will appear in the boss room after you kill the boss), or don't take any red heart damage for the whole floor. If you have gotten a devil room in the run, without the item Duality it is impossible to get an angel room, I may be wrong though. For a chance at an angel room, just don't take any devil deals and any other devil room has a 50% chance to become an angel room. This is all I know, read this if you want to know more about them: http://platinumgod.co.uk/devil-room

There's too much information that goes into how and when these rooms spawn, so just take a look at their wiki pages:

There is a useful mod called Missing Hud 2[github.com] for this game which displays a bunch of info about your stats on the left side of the screen. It also displays the chances for a devil and angel room to spawn.

Consider downloading it if you're confused. It can make it easier to understand by visually showing you the exact percentages of the chances for these rooms to spawn.

If you have the Afterbirth+ DLC, then this mod is already added to the base game, and you can turn it on in the options.

BoI is all about learning, as I can see you have AB+, so you can activate Missing Huds in options as well as a beam charger displayer.

Well for what I can recall about your question (trying to make it a bit simple):

To get devil deals, on the second floor of the first chapter do not get hit and defeat the boss while you have 100% on the devil deal (try getting soul hearts from tinted rocks or try to be careful) and pick the item that is on the floor of the Devil Room (which costs hearts and you might want to look for info in http://platinumgod.co.uk/ so you know what you are taking). This will cause angel rooms to never spawn and have a percentage each time you are in a floor to get an X% of probability on getting a devil deal (Unless you unlock Duality).

For Angel room you need to do the same as if you would do a Devil deal, however, you must go into the room after defeating the boss, do not take any active or passive item and then leave the room. At this point, when you drop into the next chapter first floor you will see there is a value on the angel rooms; it will represent the X% of probability of getting an Angel room as well as Devil room (it is a separated X%).

There are items or actions that affect the % of the rooms appearing:
+Devil Rooms:
-Pentagram
-Black Candle
-Book of Revelations
-Destroying a Beggar
-Goat Head
-Joker Card
-Teleport 2.0

+Angel Rooms:
-Rosary
-Donating 10 coins on donation machine
-Holding the Key Pieces 1 or 2 (both as well are good)
-Killing Devil Beggars, Key Master or Shell Game Beggar
-Donating to a Normal Beggar until it pays out.
-If you get "You feel blessed! fortune in sacrificie room
-Eucharist
-Joker Card
-Teleport 2.0

Hope I could help
