Which Room has D20 in Greed Mode?

[Peak Imouto]

Decided to try breaking greed mode after i unlocked the d20. Which rooms does it spawn? Gold, Silver or shop? I havent seen it in silver for ages. done like 200 resets :P So instead of risking wasting more time, I wanted to make sure if it is even possible to spawn in silver or i need to get a key for gold room, or cash for the shop.

shop has it iirc

According to the wiki, it's only in the Shop pool in Greed mode. You shouldn't see it anywhere else (unless Chaos of course).
(And treasure rooms in regular runs, but that's irrelevant since each mode has its own pools.)
