Run loot and interactables
Convert an unwanted Lunar item at Cleansing Pool
Exchange a Lunar item with a Cleansing Pool for a Pearl-family item when the trade improves the run.
A Cleansing Pool in an eligible environment layout; exact placement and availability vary between stages.
The exchange is available again only if another pool appears and you still have a Lunar item to sacrifice. Each interaction consumes an item; it is not a renewable free Pearl farm.
Stop after the trade if the desired exchange is complete or if another interaction would sacrifice an item you still need; continue to the next stage.
