I dedicated about an entire day or two just to figuring out the formula. Hope you guys can make use of it.

There are 6 variables in determining damage. They are: Power (Attack, Amp., Add. Attack), Damage Reduction (Defense), Damage Reduce, Penetration, Minimum Damage, and Add. Damage

Rules for the variables

- Power = (Base Attack x Amp.) + Add. Attack
- Power ALWAYS gets divided by 4 (or multiplied by .25) when calculating damage for PvP. ALWAYS.
- Damage Reduce (not to be confused with Damage Reduction) ALWAYS gets divided by 4 (or multiplied by .25) when calculating damage for PvP. ALWAYS.
- Damage Reduce is always (unless there is add. damage. only bladers have to worry about this.) the LAST to be calculated when finding someone's damage and always the FIRST to be calculated when working backwards.
- Damage Reduction = Opponents Damage Reduction as a Decimal, ex. For 76% reduction, use the decimal .24
- Finding Opponent's Damage Reduction = 4(Damage Done to Player with an Ability + ((Opponent's Damage Reduce / 4) - Your Penetration)) / Your Power
- Minimum Damage is not calculated the way I originally thought it might be. For now, let's ignore minimum damage altogether. Any *small* variations in damage output can be blamed on the Minimum Damage stat. For example, If you get the number 46 for Impact Stab but in game you're hitting 50-60, you can say it's because of Min. Dmg, but if you get a 46 and you're hitting 75 or higher, then the calculation is wrong.
- Add. Damage is the least used of all the variables and is most commonly found on Blader's Art of Fierceness buff. Add. Damage is ALWAYS divided by 5 in PvP. 3000 Add. Damage from AoF is reduced to 600 in PvP. In nation war it does not get divided (from what I've seen). Add. Damage is always calculated last. I won't talk about this stat more than this since it's only relevant to bladers. This stat gets calculated even after damage reduce.

Final Output: Power(Opponent's Damage Reduction)(.25) - ((Opponent's Damage Reduce / 4) - Your Penetration)

I'll show an example.

Attacker - 2425 Attack - 58% Amp. - 16% Min. Damage - 35 Penetration - Impact Stab - 15% Skill Amp. - +96 Add. Attack - 73% Total Ability Amp.

Vs.

Defender - 1500 Defense - 332 Damage Reduce - 72% Damage Reduction(72% is how much 1500 def gives)

Attacker's Power: (2425 x 1.73) + 96 = 4291.25

4291.25(.28)(.25) - 48 = 252.38

Test it out guys and let me know if you find any inconsistencies. PM me if you have questions or need help with the formula.
