I am puzzled as to the damage calculation for Asura Strike.
From online, the calculation is [(Weapon ATK+Base ATK) x (8 + SP/10) + 250 + (150*SkillLV)]*Card Effects.
Question 1,does spirit sphere add 15 attack to the Weapon ATK or the Base ATK of the calculation?
Question 2, does weapon refinement Random Bonus (0-20, for +10 chain), add 0-20 attack to the Weapon ATK of the calculation?
Question 3, assuming weapon is +0, since Asura Strike ignores defense, does Asura always do the same damage to the same target?
Thank you!
