Pile of Keys is a consumable in Godmode Achieved, a mod for The Binding of Isaac.
Spawns in Blue Womb if Blue Womb Rework has been activated, otherwise has an extremely rare (increasingly common based on how few keys there are left in the pile) chance to show up naturally.
Acts as a multiple use Cracked Key with a maximum of 8 uses.
Picking up a Cracked Key while holding any size pile and outside of a Curse Room will add it to the pile Isaac is currently holding, up to 8 Cracked Keys.
