The chance for a stone to be a metal ore (copper, iron, gold or iridium) will vary depending on floor, starting at 2% on floor 1, rapidly increasing to 16% on floor 100, and then increasing to 100% on floor 1780. Luck has no effect on this chance, or on the ore distribution. Copper and iron have the same distribution. From floor 2010 only [[Gold Ore|gold]] and [[Iridium Ore|iridium ore]] will be found, and from floor 5700 only iridium ore will be found from this generation. | The chance for a stone to be a metal ore (copper, iron, gold or iridium) will vary depending on floor, starting at 2% on floor 1, rapidly increasing to 16% on floor 100, and then increasing to 100% on floor 1780.
