Angel Rooms not guaranteed
So It is my understanding that in Repentance, you should get a 100% guaranteed angel room as long as you don't enter a previously generated room. (example: on B2 a devil room generates and is earned, you don't enter and on C1 you should get 100% angel room so long as you don't take red heart damage)

However I am seeing run after run (already quite a lot) that this conditions meet, but I get 66.7% or 33.7% chance on the angel room. Happening particularly with Samson or ??? baby

it's not guaranteed angel when skipping devil. It's guaranteed angel if it spawns after the boss fight.

Yeah what I mean, if on Basement 2 I get a devil room, I don't take it. So shouldn't it be on Caves 1 a 100% chance for an angel room? or am I misunderstanding you

People are misunderstanding the mechanic:

The mechanic guarantees that if you skip the first devil room entirely that the next Angel/Devil room will always be an angel room instead.

It does not effect chances of getting said room however*.

@backstabba so it's not a guarantee spawn of an angel room, just a guarantee that it "IS" and angel room if it spawns?

No, the chance for the 2nd devil OR angel room to spawn is still the usual ~33% on the next floor whether you go in the 1st devil room or not. However if you go in the 1st devil room, it's a ~16.5% chance to get a devil room and ~16.5% to get an angel room. If you skip the 1st devil room, it's just a ~33% chance to get an angel room.

Exactly. *If* you earn another room after the boss, it *will* be an angel one.

Got it, so it's confusing how the mechanic was laid out, but seeing it that way it does make a lot of sense

And to clarify, skipping the first devil room means not entering it at all. Even through red chest teleports or Joker.

Nope never has been guaranteed to get an angel room even before the DLC. What you want to do is up your chances by building Angel room karma. To be honest before the DLC the first room miss gave you 50% after missing it while I believe it's now 35% on the Karma. You also still get less rooms if your Devil Room Karma is down and before you didn't lose Angel room Karma just because you got hit so it's actually now a bit harder to gaurantee getting angel rooms. All missing it does is raise the karma a bit. A lot of the old methods of building angel room karma are still there like using the sacrifice room. You can now get the confessional also that will raise Angel Room Karma for the cost of life. You need to beat Mega Satan with tainted Bethany though. Also curse rooms won't deduct karma now nor blood donations but that's mostly important for Devil Rooms.

So he actually nerfed people by punishing them for going into the first devil deal and getting the free soul hearts and junk?

Yep you have to completely miss it I believe. I'd say if you want to get as much Angel Rooms your best bet is to unlock the Confessional asides the sacrifice room. The confessional is like a blood donation machine that gives you chances to raise your good karma a bit when using it.

It's interesting to see how on a "single player" game we got so many nerfs to the "fun" stuff

Yeah, sort of, I don't think this change was done specifically to nerf devil deals (that's what adding all the crap in the item pool and nerfing things like brim/maw/dark bum was for. this change was likely done to make angel room(s) easier to get outside of a random chance) but yep, it did indirectly make going for the first devil deal a really bad idea. Given all the other changes to devil deals now, it's way too risky to give up a guaranteed angel spawn just for the small chance you'll get something worth taking at all.

I think Devil Bum was nerfed because it was almost the item that made you invincible and overpowered and broke your runs. A lot of the nerfs seemed to be revolved on trying to prevent runs getting broken with those items. Guppy's nerf doesn't exactly feel like much of a nerf but I've been rarely able to make guppy with Repentance as I use to have it all the time. It's nerf was from getting blue flies every time your tear hit to now being 50% of the time. Still really OP in regards of the slight nerf. Brimstone is more noticable on stronger enemies but now if you get icepac it doesn't just look like a green beam and blows up everything your beam hits so that might have lost it's damage b 3 attack but brimstone seems to have some noticable changes with it synergy. In regards though Devil rooms generally broke your run and devil bum supported those rooms a lot. I think that was the noticable difference with devil rooms and their items and deals. I feel like the confessional might be the entire reason for the Angel Room changes though. Like if you donate hearts you can get your angel room room karma maxed with enough life. you don't get karma every time you donate life but you can keep using and getting more and more on use until it breaks.
