Where
WSC: Secondary attribute like STR 30% (30% of your STR) (See individual Weapon Skill)
fTP: TP Multiplier (See individual Weapon Skill)
fINT : function of your INT and target's INT
for WS, fINT = 8 + ΔINT/2
ΔINT : difference between your INT and target’s INT (caps at 24 for WS)
Resist : Possibilities are
No Resist(1/1)
Half Resist(1/2)
Quarter Resist(1/4)
Resisted(1/8 and 1/16)
Void(0)
Weather
if WS is used in single weather effect = 1.1 (+0.1)
if WS is used in double weather effect = 1.25 (+0.25)
Conversely, if WS is being used on the day where WS element is weak to, the multiplier is reduced by 0.1 and 0.25
MDIF : ratio of your Magic ATK to target’s Magic DEF (Matk/Mdef)
Magic Damage Adjustment : (1 + or - (Shells, Shining Ruby, sum of magic damage cut equipment))
This parameter have denominator of 256 (1/256), for example
Shell I is -24/256, Shell II is -36/256, Shell III is -48/256
Shell IV is -56/256, Shining Ruby is -10/256, Bubble Curtain is -128/256
The smallest Magic Damage Adjustment number given by equipment capped the multiplier to 128/256 (0.5)
Certain magic damage adjustments of particular monster family have been found:
Ebony Puddings in Mount Zhayolm appear to take 25% bonus magic damage (+64/256).
Eo'ghrahs in Grand Palace of Hu'Xzoi appear to take 87.5% magic damage (-32/256).
Demon, Ahriman, Corse, Cardian have 25%(-64/256) magic damage cut
Evil Weapon have 12.5%(-32/256) magic damage cut
To some particular HNM, magic damage cut can occur occasionally when using the same element against that of HNM
