Help Needed For Calculation

Melee order was: attack > dragon gems > stig > proficiency > skill multiplier minus flat defense multiplied by bp reduction > torts > bless reduction. That *crit if it does and ending with the final p attack - final p defense.

Magic order was: m.attack > phoenix gems > skill multiplier (gets no bonus from backsword levels) minus mdef > mdef% > bp reduction > torts > bless. That *crit if it does and ending again with final m attack - final m defense.

Archer bow works completely different. It's: attack * dragon gems > stig > proficiency (not for scatter) > skill multiplier minus entire enemy dodge values (values are actually %'s, usually around 90%) > bp reduction > torts > bless. Ends with final p-attack - final p-defense.

Double BattlePower = Attacker.Potency - Target.Potency;
BattlePower = Math.Pow(2.0, BattlePower / 100.00);
Damage *= BattlePower;
