Now with damage, FyrosFreddy had the correct formula for 2h sword- I'm sure the other are close enough too. However, I'm going to use the 2h sword formula with the weapon damage factors for the KC post craft stat, it might be the closest we can get to game and only requires changing 1 number at start of formula- I did not put the Floor function, I'm not sure if just the display drops the decimal or if it reduces dmg...
Damage = <Dmg Factor>*(26+<quality>)*(100+<precraft>)/100
Damage = <Dmg Factor>*(26+<quality>)*(100+<precraft>)/100
