Attack rating is a secondary attribute which refers to your physical accuracy. It is influenced by Secondary Attributes, certain weapon bonuses, Accessories, garnments and certain buffs. The higher your attack rating is, the most likely you are to deal critical hits and the less likely you are to miss your attacks.
Your weapon's balance affects the effectiveness of your attack rating in regard of your physical accuracy. Higher balance will result in more critical hits and fewer misses for the same Attack Rating value.
Your opponent's dodge will affect both your chances of dealing critical hits and missing. An high dodge for the opponent results in fewer critical hits and more misses from you.
Chi Kung Attack Rating
Chi Kung attack rating is a secondary attribute that is the Attack Rating's equivalent for Chi Kung. It is influenced mainly by your Wisdom but also by certain Accessories, special bracers such as Wan Daye's, and Clothes. The higher your Chi Kung attack rating is, the most likely you are to deal critical hits when using Chi Kung techniques, and the less likely you are to miss your chi-kung attacks.
Chi Kung Dodge
Your opponent's chi kung dodge will affect both your chances of dealing critical hits and misses the same way dodge affects physical attack rating.
