As the skills level goes up, the amount of hits you'll do, as well as overall damage, will increase. 2 spheres are required to use this skill. If the caster still has at least one Spirit Sphere, he can follow up an Asura Strike. The longest possible combo a Champion may use is Raging Trifecta Blow -> Raging Quadruple Blow -> Raging Thrust -> Tiger Knuckle Fist -> Chain Crush Combo -> Asura Strike, provided he has the necessary Spirit Spheres. The Damage is 400%+100*SkillLV% ATK.
