---Physical Attack Damage

2. If weapon Attribute is strong vs Enemy, Attack = Attack x 1.5
3. Defense = Stamina + armor{Defense} + GeoEffect/10 + DefUp
4. Final Damage = AttackDefense
5. If Critical, Final Damage = Attack x 2.5 – Defense x 2.5

--Probability of a Critical Hit

2. Critical Avoid(%) = Skill/2 + armor{Critical Avoid}
3. Final Critical Rate = Critical Rate(%)Critical Avoid(%)

--Double Attack (if Counter is enabled)

*Only the attacker can double. Retaliation attacks will not double.
