13 x 70% pass = 6 fail = 1 boom = 6 Rip 6 maple earring. Can’t even land 3 70% on any of the 6 piece.
I feel like Maplestory's success calculation is done in a way to prevent success or has a different rate than advertised but that's just me. I know someone had posted an image of a true success rate for Chaos Scrolls for Kms or something and it was like 1% chance of getting +5.
