Regarding critical damage with the revamp

Maybe the min is based off the rounded max.

(211*4+45)*1.6*.66 = 938.784 rounds to 939, 939*0.45 = 422.55 rounds to 423.

Yeah, that's why I specifically based the MIN damage on the MAX, rather than a clone of the formula.

If you want to be more accurate on the MAX formula, you could add 0.5 to the result and truncate.

MAX = (int) (6.4*DEX + 1.6*STR)*(ATT/100) + 0.5
MIN = (int) (base mastery + mastery % * MAX
