Boss Challenge Room's Incomplete[]
Dross II definitely has a chance to spawn Clog, who I think has a 50% chance to replace Lil Blub. Ashpit II has a chance to get Singe (I think in the second wave). Corpse II also has a Boss challenge room, which is not listed here. It can spawn 2 Chub's on wave 1 and The Scourge on wave 2. This was on a run where I had already fought Rotgut and Chimera (with forget me now), so maybe the 2 Chub's replaced one of those. These are just three incomplete pools I've noticed, it's possible that there are more. -Smugless (talk) 20:25, 23 May 2021 (UTC)
Spawn Locations For Waves[]
It might be nice to add possible spawn locations for each wave, as it can be really annoying to have an enemy spawn on Isaac, especially for players who have never encountered certain waves before and have no way of knowing the possible locations for the waves to spawn. -Smugless (talk) 20:31, 23 May 2021 (UTC)
Secret Room with Greed interaction[]
I was always under the assumption that if you find greed/super greed, even before repentance came out, in the secret room next to a challenge room that the boards will remain, and that this isn't a bug or a new interaction and it's marked as both at the moment and I don't just want to go edit something without being 100% sure about it.
