I'd done some experiments.

google spreadsheets: spreadsheets/d/19Arc7ogKlfMlFSrngRpn4TbHuT0lGJ_GA5jwpmGpYRE

damage formula = (Effective ATT * BAL + Additional damage multiplier * Additional damage * BAL) * skill multiplier

Effective ATT: A function of ATT, DEF and ALR. (ATT-DEF) is capped at 10,000 if there is no ALR.

BAL: (balance/100 ~ 1.00) with step 0.005

Additional damage multiplier: vary by ATT, DEF and ALR. When ATT is over ATT cap and no ALR, this value ~ 6.25.

When there's no additional damage, the precise Effective ATT can obtain by raw_damage_calculator because the possible value of damage is limited.

3rd order polynomial can fit the data quite nicely with error < 0.01%.

The formula by Ainama in 2013 can fit too with error < 3%.

There's a newer formula in 2015, but I don't fully understand...

The effect of additional damage can be obtain by subtracting effective ATT from raw ATT. Sadly, the raw ATT is no longer obtain by raw_damage_calculator. My guess is that there's a separated balance roll in additional damage part, so that the damage value is spread. So I have to use more data to get a more reliable value.

The multiplier is quite linear to (ATT-DEF) when (ATT-DEF)>3000.

The statement "Effectiveness of additional DMG will vary by your ATTand monster's DEF" seems correct.

This is the part that I'm not sure about. The data point is few and error is larger compare to the above 2 experiments. But a least it shows that ALR affects Additional damage multiplier as well.
