DEBUFF BESEKER

Agreed Reckoning has 518% x 4 damage per hit which is 2,072% and it hits twice for a total of 4,144% damage. And if you max charge this skill it doubles the damage and that is 8,288% of damage in just a single skill!

Sura's Afterimage is the only skill that comes second to reckoning it only deals between 4,000% to 4,500% already including the flow damage and its animation and cast speed is so slow that its equivalent is like casting 3 skills from berserker including reckoning.
