Usable only when critical_explosion is active.Uses all SP to do massive damage to the target, HP/SP will not regenerate naturally for 5 minutes after Asura Strike is used.
Cancels critical_explosion after use and requires all remaining Spirit Spheres (that is all 5 if cast independently). Damage is [(Weapon ATK + Base ATK) x (8 + SP/10) + 250 + (150 * SkillLV)] * Card Effects.
Can be used while catching someone using LV 5 blade_stop or with no Cast Time at the end of a combo attack (triple_attack → chain_combo → combo_finish → Asura Strike) but the critical_explosion and Sphere requirements remain in both cases (usable with the 4 spheres remaining after activating blade_stop/combo_finish).
Increasing the Asura Strike skill level has a relatively small effect on total damage compared to increasing SP, int or str. This skill can be interrupted.
