To know how much Power you will roll, you will need to glimpse at this formula:
rolled_Power= (powerFromLevel * (1 + 0.0025 * ( ( totalMatchingElement * 1.07) + (totalPwrFromWeapon * 1.03) + (totalNonmatchingElement) ) ) + bonusPowerFromReforging) * random_between(0.9, 1.1)*(1+(opponent_elementadvantage+char_matchadvantage)/100)
Now, lets dissect this formula element after the other:
Power from each level
PowerFromLevel can be gotten from the image to the side, and the total matching element will be the sum of the subskill powers, i.e.
For Weapon A(image attached below),
the Blades Element is Earth, so the matching Element is DEX. => the totalMatchingElement = 365
TotalPwrFromWeapon is the value of PWR if the weapon has it, else zero => totalPwrFromWeapon = 300
totalNonMatchingElement = sum of all subskills that do not match the element of the weapon, => totalNonmatchingElement = 386
bonusPowerFromReforging is the total power that will be added when reforged, checkout weapon B for this weapon since it is not reforged: bonusPowerFromReforging = 0
random_between(0.9, 1.1) generates a random number everytime you play between 0.9 and 1.1
opponent_elementadvantage = 7.5 if your character's element is the active for your opponent's character's element, and -7.5 if your opponent's character's element is the active for your character. the actives can be gotten from the image:
The analogy you could use is: Fire BURNS Earth, Earth ABSORBS Lightening, Lightening IONISES Water, Water COOLS Fire.
char_matchadvantage = 7.5 if your weapon's element matches your characters element and 0 if not.
So Assuming I had an Earth character (Level 30), with weapon A, and I was fighting an opponent whose element was lightening, I will roll:
(powerFromLevel ( = 3870) * (1 + 0.0025 * ( ( totalMatchingElement(= 365)* 1.07) + (totalPwrFromWeapon(= 300) * 1.03) + (totalNonmatchingElement( = 386) ) ) + bonusPowerFromReforging(= 0) * random_between(0.9, 1.1)*(1+(opponent_elementadvantage(=7.5)+char_matchadvantage(= 7.5))/100)
Rolled power will therefore be between (14875 and 18181)
if you were fighting an opponent whose character' element was fire, your roll range will be between (13808 and 16877)
so if you Were using weapon B and fighting an Earth opponent, and you had a lightening character( level 37), your roll will be as follow:
(powerFromLevel ( = 5440) * (1 + 0.0025 * ( ( totalMatchingElement(= 0)* 1.07) + (totalPwrFromWeapon(= 366+305) * 1.03) + (totalNonmatchingElement( = 337) ) ) + bonusPowerFromReforging(= 660) * random_between(0.9, 1.1)*(1+(opponent_elementadvantage(= -7.5)+char_matchadvantage(= 7.5))/100)
rolled power will therefore be between (19294 and 23581)
So this is the power that Weapon A will Roll as the character used levels up:
This wiki was too long already, so I decided to make a new wiki for how much you will earn: How much Skill will I Earn as I level up?
