according second post on this site:
quote: "What about the weapon? Well, you have 125 damage to start with, but this gets tweaked in a number of ways. The base weapon attack (before refinement) is adjusted a couple of times. Str affects your weapon attack. 1% increase per 2 str, actually. So with 100 str, the weapon attack goes up 50%. Next we have "variance". Level affects the variance. Your weapon will get plus or minus 5% for every level of the weapon. So a level 4 weapon can do 20% less or 20% more than its base value."
if you need formula:
WeaponATK = floor[((BaseWeaponDamage + Variance + StatBonus + RefinementBonus + OverUpgradeBonus) × SizePenaltyMultiplier]
let's take a look at my example.
I have combat knife with 80 weapon ATK.
So BaseWeaponDamage= 80
Next on the list
Variance - i can remove this parameter because I am using Maximize Power(Blacksmith Skill).
So Variance = 0
StatBonus - this parameter that affected by my str(see quote)
I have 130 str(see screenshot). it means my Weapon ATK increasing by 65%.
StatBonus = 80ATK*65%
RefinementBonus = 0 and OverUpgradeBonus = 0(Combat knife haven't upgrade)
SizePenaltyMultiplier - I am remove by Weapon Perfection(Blacksmith Skill), so it doesn't affect
WeaponATK =(80 + 0 + 80*65%+ 0+ 0)* 1 = 132 ATK.
and my damage will be:
Now Let's using Blacksmith Shadow armor and this bonus:
this bonus give me 6% to Weapon ATK.
and WeaponATK = 132+6% = 139.92 ATK
difference with set about 8ATK
So my damage change since 556 to 562( i don't know why 563 but it's close)
What we can see:
So my damage in full Blacksmith Shadow set must be about 566. But is't not working:
