    Default Complete formulas ?

    Hello,

    I did a bit of searching but couldn't fine an exhaustive list of formulas of how exactly the damage done is calculated (reisstance/buff/debuff order and so on).

    For now I assume it's (RawAbilityDamage) * (1 + active buffs) * (1 + debuffs) * (1 - target mitigation).

    Can anyone validate/invalidate this ?
    I'm interested in any kind of formulas (already have what is on this thread).

    Thanks in advance !

    All of the different categories you listed are multiplicative. The target's mitigation is actually has more than one component, though, all of which are also multiplicative: you have armor/resist, any passive mitigation, and any buff-based mitigation. There's also Valor, if you're in PvP.

    Also, if there are any debuffs on you that reduce (or increase) your damage done, those will also be multiplicative.

    Finally, there are a few effects that mitigate damage taken but aren't quite "normal" mitigation, such as Rift Guard (an absorb shield which soaks up a percentage of the damage that you take) and links. These are also multiplicative, but the relevant amount of absorbed/intercepted damage is calculated after everything else. The order of operations doesn't matter for the amount of damage that the target will take, but it will affect how much damage is taken by the person that applied the link, or how much of the absorb shield's capacity is consumed.

    If the multiplicative thing for debuffs is true:

    Spell Damage = (BaseDamage + Spellpower * Spell Coeff) * (1 + sum of passive damage gains[damage gifts from talent trees and flat damage increases that do not show in the buff bar]) * (1 + sum of all active damage gains[Everything that's related to buffs]) * (product of all debuffs that affect damage taken) * (1 - Spell School Resistance * (1 - Spell Penetration))
