Calculating Weapon Skill Damage

See also Weapon Skills

Magic-Based Weapon Skills

 * Damage = ((WSC * TP) + INT/2 + 8) * MDIF * ELM
 * Where
 * WSC: Secondary attribute like STR 30% (30% of your STR) (See individual Weapon Skill)
 * TP : Multiplier (See individual Weapon Skill)
 * INT : difference between your INT and target’s INT (caps at 24)
 * MDIF : (your Magic ATK/target’s Magic DEF)
 * ELM : Elemental influence (i.e. is target weak or strong to the element)?

Physical-Based Weapon Skills

 * Damage = WD * PDIF = ((D + fSTR + WSC) * fTP) * PDIF
 * Where
 * WD: Base damage of your WS
 * D: Base damage of your weapon (e.g., Espadon = 43)
 * fSTR: difference between your STR and target's VIT
 * WSC: Secondary attribute like STR_30 (30% of your STR).
 * fTP: Multiplier (Please see chart below).
 * PDIF: (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


 * For example, suppose you are level 67 and have 100 STR and 100 MND and use use Swift Blade (STR 30%, MND 30%).
 * WSC = integer[(100 x 0.3) + (100 x 0.3)] x @ = integer(60) x @ = 60 x .86
 * (@ is 0.86 - 0.87 at LV67)

Note: Suspected that for Sneak Attack with THF main, the calculation is WD = (D + fSTR + WSC) * fTP + DEX + AGI
 * WD = (D + fSTR + WSC) * fTP
