I am at the third cave. It shows that I have 67% chance dropping Stone, 25% chance Copper and 17% chance dropping Tin . 67 + 25 + 17 = 109% But sometimes I still received nothing . That's so weird. Maybe a typo, 57% Stone?
How you can calculate probability like this o_O ? "67 + 25 + 17 = 109%" this is not the good formula to calculate probability
