Xl Boss Rooms.

Are the larger boss rooms not capable of spawning Devil or Angel Rooms?

I've had several 'perfect' (no damage) boss kills in them, and I'm not getting ♥♥♥♥.

devil room and angel room chances are only altered by multiple factors, not getting hit in a floor doesn't garantee a devil/angel room, only makes the chance higher, only the goat head item can make the chance 100% every floor except sheol/cathedral and up.

I know that.

But I've NEVER gotten a Devil Room on an XL Boss Room, and I've had more than a few times where I had high odds of doing so.

You mean the double trouble Boss Rooms? You can have Devil/Angel deals, I don't get those kind of Boss Rooms often but usually I get one right after having beaten the bosses.

Not the two seperate boss rooms on an XL floor, but the boss rooms that are double the size of a normal boss room.

Yes, and you fight two bosses in the one room, right?

You can absolutely get devil/angel rooms from them.

That's not entirely true.

Not getting hit at the boss = +35% chance and not getting hit on the entire floor = + 75% chance.

Those 2 chances are individual, which means getting no red-heart damage on the entire floor actually gives a +110% chance. That's why you ALWAYS get a devil deal on floor 2, if you've taken no red-heart damage on the entire floor.

If you've seen a devil room on the previous floor, that would get multiplied by 0,25, turning a 110% chance to just a 27,5% chance. Seeing one 2 floors ago still multiplies your current chance by 0,5, resulting in a 55% chance, if your current chance would be 110%.

Of course, that chance can be raised. Blowing up shopkeepers gives +10%, having Black Candle or Pentagram give you another +10% each, etc.

Also, devil rooms can spawn just fine on large boss rooms, as well as on tiny ones. You just got bad luck there.
