Patch Available - KMST 1.2.456

someone give me the damage a mercedes with 2M range does with RoI please, quite sure it doesn't even come close to 10M a hit

If you don't have boss damage, you're hitting ~3.6m per non-crit, ~4.9~5.5m per crit.
If you have 100% boss damage, you're hitting ~5.8m per non-crit, ~7.9~8.7m per crit.

But obviously, Mercedes with its 110% base damage Ring of Ishtar is the prime example of a class that will reach the 50m cap, not something like a Fire/Poison Arch Mage, or Hero.

Not saying they can,because I haven't done the math, but they are significantly more likely to hit that high.
