Want to ask something?
The percentage success or fail is per hit or per anvil?
if per hit is not fair i think, for example you need to have 3 time success to be success anvil +1,
but 1 of 3 fail become fail -1 whatever in the 1st hit, 2nd or 3rd hit.
if percentage RNG is per anvil so IMC setting fail is in the middle of 1st 2nd or 3rd hit, is that?
which one?
