angel rooms don't spawn

[Xalerons]

hey everyone so just a minute ago i got 100% chance of an angel room thanks to the sacrifice room so i went and killed the boss and no angel room spawns i've also been having issues where devil rooms spawn over a high percent angel room chances so i think its safe to say angel rooms are bugged. has anyone else been having these issues? if so feel free to chat about it i thought i would share this with everyone also yes my grammer is ♥♥♥♥ but oh well!!!!

The Angel chance % only signifies your chance of getting an Angel room over a Devil room if you get a deal. The HUD element that seems to represent the Devil chance is really just showing your chance of getting a deal at all for the floor. So to guarantee an Angel deal, both would need to be 100%.

If you've previously been to the devil room, via a red chest or some other means, then the angel room won't appear on that floor even with the Sacrifice buff.

Or as gatto said, were you misreading your chance? The top "devil room" chance is the chance of getting a deal at all and the bottom angel room chance is the chance of getting an angel room, only if you qualify for a deal in the first place.

no no i was in caves one cleared out the floor without fighting the boss then i found the sacrifice room so i decided hey i'll get the angel room buff here and fight the boss however after i fought the boss no angel room spawn even tho it had a 100% chance and yes i know about percentages the top was like 50 so yeah i found it odd

Which means you had 50% chance to get a deal, and if you got one, 100% chance to get an Angel. You failed at the first part, so no deal for you no matter which one.
"I know about percentages". Heh.

If you had 50% devil and 100% angel on the HUD then the actual rate is 0% devil room and 50% angel room.

Devil room chance is devilhud%*(100%-angelhud%) and angel room chance is devilhud%*angelhud%. Chance for either is just devilhud%.

The duality item also allows both to appear (but only 1 to be entered), but the formula doesn't change - just if you get one of them then it tries to add the other one as well - doesn't always succeed however - for instance if there's no valid space to add another door.

Well i had 100% angel room chance and 63% devil deal chance and ended up getting the devil deal

You'd probably already entered the devil deal room somewhere on that floor before getting 100% angel room chance - once one of the rooms is entered (e.g. via a joker card or red chest teleport or simply by beating a boss and entering the door) on a floor the other one can never appear on the floor regardless of chances as they are technically the same room on the floor, they just appear differently.

nah never found a joker card on that floor and did touch red chests 'cause i was after angel rooms

The only other things that can bypass the %s as far as I'm aware is failing to meet the angel room criteria - namely having seen a devil room door spawn on a previous floor and having not taken any devil deals yet.

The only way to bypass these requirements is with the sacrifice room blessing/teleport and a few specific items that can force one or both to appear, though they still require that a devil room hasn't been found on the current floor already..

PS: Devil deals are defined as any health cost to buy items - these appear in the black market secret area as well as devil rooms.

i had taken a devil deal on the earlier floor but on the floor with 100% angel room chance i had spammed the sacrifice room and killed both angels

[Daemonologist]

The angels are irrelevant, as their chance is ignored due to the devil deal taken previously. It's only the 2 "you feel blessed" parts - 3rd sacrifice is 15% chance if it triggers and 5th sacrifice is 50% chance (stacking additively to 65% if you get both as it's only 1 dice roll) if it triggers. Even if you get both though, this is just one 65% chance because the devil deal you took wipes out the rest of the chances which are rolled separately.

The 6th sacrifice also has a small chance to teleport directly to the angel/devil room - if you haven't entered it on this floor yet it's guaranteed to be an angel room. This is less likely to occur than the blessings are however.

There's one other thing to note as well - if you donated to a devil beggar until it gave an item on that floor then there's a 10% chance from a dice roll that the room generated will be a devil room, which bypasses the usual rules much like the sacrifice room's blessing dice roll does.

Of course it's also possible that the hud is simply calculating it incorrectly or not factoring in certain rules - dice rolls are separate and therefore stack multiplicatively in general so it should be quite difficult to reach 100% angel room chance without certain items that guarantee angel rooms after all.

Only taking a deal with the devil counts against an angel room spawning. You can open red chests without any problems.

Technically you're both right - but you're talking about different things.

valzyf is saying if you've entered a devil room on a floor by any means (e.g. red chest teleporting you there) then there's no way to make an angel room appear on the same floor, not even via the sacrifice room. This is because they're actually the same room, so only one can be generated per floor.

On the other hand you're talking about chances of angel rooms spawning on later floors - in which case yes, only taking devil deals counts against you - or more specifically: paying for them with red heart containers/soul hearts - if you duplicate the item (e.g. diplopia, crooked penny) or otherwise get them for free (e.g. credit card) it doesn't count against you still
