Changes

If a Qi quest is in progress which makes the mine more dangerous, there is a small chance for a stone to be replaced with a radioactive ore. This is very dependent upon luck, with the luck boost from the special charm being worth 192 floors, and the worst luck requiring a depth of floor 550 to have any chance ore will drop. This is also dependent on luck buffs, with each level of luck worth 15 floors. This will replace any of the below stones.

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 affect on this chance, or on the ore distribution. Copper and iron have the same distribution. From floor 2010 only gold and iridium ore will be found, and from floor 5700 only iridium ore will be found from this generation.

If the stone is not a metal ore, there is a chance for it to be a a gem stone ore (diamond, emerald, aquamarine, ruby, amethyst, topaz and jade), a gem node (the round purple stone), a mystic stone or a dark grey rock. This means that the chance can decrease as you go deeper as more of the stone is metal ore, and above floor 1780 these will not be found.
