Damage = WD * PDIF = ( D + fSTR + WSC) * fTP * PDIF
Where
WD: Base damage of your Weapon Skill
D: Base damage of your weapon (e.g., Espadon = 43)
fSTR: function of difference between your STR and target's VIT
WSC: Secondary attribute like STR 30% (30% of your STR)
fTP : TP Multiplier (See individual Weapon Skill)
PDIF: function of (your Physical ATK/target’s Physical DEF)
WSC = integer(any secondary attributes) x @
Level @
Lv75... 0.83
Lv74... 0.83
Lv73... 0.84
Lv72... 0.84
Lv67... 0.86 or 0.87 (perhaps 0.87)
Lv60... 0.90 or 0.91 (perhaps 0.90)
Lv40... 0.94
Lv37... 0.94 – 0.99
Lv31... 0.94 - 0.99
fSTR is the damage bonus/penalty from your STR - monster VIT for melee attack
fSTR is calculated by fSTR2/2. So, melee attack needs roughly 4~6 STR to increase fSTR value by 1
When STR-VIT value is high, fSTR can be approximated by ((your STR - monster VIT)+4)/4
fSTR's lower and upper cap values are affected by weapon rank
The lower cap of fSTR is - Weapon Rank
Exception: Rank 0 weapons have lower cap -1.
The upper cap of fSTR is ( weapon rank+8).
