I know exact percentages aren't known bc Neon hasnt released that info yet but am really used to regular maplestory and the %s help a ton. I know the % of success decreases after every succuessful upgrade. Could it perhaps be the odds are just cut in half every time? +1: 100% +2: 50% +3: 25% Also not every fail breaks the item, I would say maybe 50% chance? +2s seem to be easy and +3s I haven't gotten past that. Thanks.
