Magic ore ｢魔鉱石, makōseki｣ is the raw form of magisteel. Even without being processed into magisteel, it is considered equal in value to gold due to being rare and versatile.[1]
Unlike regular ores, magic ore only forms around the vicinity of B rank monsters or higher. That's because when over a certain period of time regular mineral ores are exposed to dense concentrations of magicules, the ores will slowly absorb them and eventually turn into magic ore.[1] Due to the high level monsters lurking around them, they are only accessible to high ranking adventurers.[1]
Magic ore is already very difficult to obtain, but the amount of magisteel that can be extracted from that ore is only 3~5%. In other words, even a fist-sized chunk of magisteel is worth at least twenty times its weight in gold.[1]
The 91st floor of the Dungeon is designated as the storage place for mineral ores, allowing them to turn into magic ores after absorbing Veldora's magicules.
