For this, the luck boost from the special charm (0.025, contribution to AverageDailyLuck) is equivalent to an additional 192.3 floors (2500/13), and a single point of luck (such as from a food buff) is worth ~15 floors. With the best possible luck 1.35% of stones will be radioactive ore. With the worst possible luck no radioactive ore will appear until floor 550. Also note that radioactive ore will not appear on any floor divisible by 5. | For this, the luck boost from the special charm (0.025, contribution to AverageDailyLuck) is equivalent to an additional 192.3 floors (2500/13), and a single point of luck (such as from a food buff) is worth ~15 floors.
