The guild Ainz Ooal Gown manage to produce a Caloric Stone once from one of the prismatic mines,the Celestial Uranium mine. The Celestial Uranium contain one of the seven prismatic ores which is a critical element for the Caloric stone. These ores can be mined and sold in the YGGDRASIL markets and the tapped-out mines in YGGDRASIL would slowly recover and be ready for further harvesting. Once the ores is in the YGGDRASIL markets, it would drive up the price due to it rarity. Only by stockpiling large amount of prismatic ores would it trans-mutate into a Caloric Stone.
