En cuanto pueda meto formulas, pero les aviso q es UN BARDO este skill...

Main Weapon dmg (normalized) + 101 * 1.4 (opportunity + poisoned target)
Off Hand Weapon dmg (normalized) + 101 * 1.4 (opportunity + poisoned target)

Main + Off = Mutilate final dmg
Mutilate crit = Mutilate final dmg * 2.3 (with lethaly)
