How to calculate damage in battle

Damage = (playerATK + equipmentATK + SkillPower - targetDef) * comboRatio * elementalRatio * CriticalRatio

| Total Damage = Player ATK + Equipment ATK + Skill Power |
+----------------------------+----------------------------+

+----------------------------+----------------------------+
                             |
                             v
+----------------------------------------------------------+
|         Damage *= Combo Ratio (ComboCount * 100%)        |
+----------------------------+-----------------------------+
                             |
                             v
