Firstly define some variables: A = Basic Attack Power B = Skill Attack Power C = Attack Power Increasing rate D = Enemy's total accessories Absorption rate E = Enemy's Defence Power F = Balance rate G = Total Damage Increasing rate H = Skill Attack Power rate A final damage formula: Damage = ((A + B)*(1 + C)/(1 + D) - E)*F*(1 + G)*H Use the screenshots to Prove(European Warrior vs. European Wizard) : European Warrior Details(according to the screenshot): Basic AP: 3829 ~ 4538 =>We choose its max value 4538 Skill AP: Turn Rising, Physical AP 1210~1478(208%) => We choose its max value 1478 Attack Power Increasing rate: (Two-Handed Sword passive skill, Physical AP + 99%) => 0.99 Balance rate: use the balance formula below => 1.07788162 set M = 28 + Char.Lv*4 then Phy.bal = 100 - 100*2/3*(M - str)/M, Mag.bal = 100*int/M Total Damage Increasing rate: One of the equipments has a a Damage Increaing rate of 5% => 0.05 Skill AP rate: Turn Rising, Physical AP 1210~1478(208%) => 2.08 Total accessories Absorption rate: 1.009 Defence Power: 2179(Mag. Def) European Wizard Details(according to the screenshot): Basic AP: 6964 ~ 8138 =>We choose its max value 8138 Skill AP: Meteor, Magical AP 2052~2508(439%) => We choose its max value 2508 Attack Power Increasing rate: ( Passive skill, Magical AP + 100%) => 1.00 Balance rate: use the balance formula below =>1.13084112 set M = 28 + Char.Lv*4 then Phy.bal = 100 - 100*2/3*(M - str)/M, Mag.bal = 100*int/M Total Damage Increasing rate: One of the equipments has a a Damage Increaing rate of 5%, Skill Life Turnover add 25%=> 0.30 Skill AP rate: Meteor, Magical AP 2052~2508(439%) => 4.39 Total accessories Absorption rate: Left Ring:23.5% + Right Ring:23.7% + Necklace:30.5% + Earring:26.2% = 103.9% => 1.039 Defence Power:1380(Phy. Def) Damage Values Calculation: European Warrior -> European Wizard Damage = ((A + B)*(1 + C)/(1 + D) - E)*F*(1 + G)*H =((4538+1478)*(1+0.99)/(1+1.039)-1380)*1.07788162*(1+0.05)*2.08 =10573.24 European Wizard -> European Warrior Damage = ((A + B)*(1 + C)/(1 + D) - E)*F*(1 + G)*H =((8138+2508)*(1+1)/(1+1.009)-2179)*1.13084112*(1+0.3)*4.39 =54335.78 See the screenshots below: The two damage values are: 10576 and 54348 You will find that the real damge values are a bit higher than the values I calculated, because I only use the integer to calculate, such as AP, Defence Power, accessories absorption rate etc, they have been round up before showing to us.

g859 says: This guy is saying that this is the real deal. Looks legit, he got the same results that he calculated in game. Formula makes sense too. I dunno, looks like Emulator devs just caught a break. Eckoro; says: hm ty for link, il tell you how it goes later. g859 says: Kk, I can't wait Eckoro; says: well not really a break as such just more accuracy = more authentic gameplay.

For example, the damage formula is going to help people calculate damage done to each other, and especially in the fact that emulators now have a concrete formula to use. It's just a hobby, but quite an intricate one at that.
