Talk:Cracked Key

Potential additional requirements for spawning.
I'm not sure if it's just some sort of bias in my memory, but I think that you may also need to full clear the reverse floors in order to spawn the red key. It's only appeared when I've full cleared the reverse floors. --SpectreSkirt 03:38, 8 April 2021 (UTC)

Trinkets left in boss rooms transform into a cracked key during that ascension. It can also just spawn as a normal drop like cards do. StackedMan (talk) 04:22, 8 April 2021 (UTC)
