Armor Penetration Rating
Armor Penetration Rating effectively increases the damage dealt by most of your attacks by reducing the damage reduction incurred from a target’s armor. Every 13.986 points of armor penetration rating grants you 1% armor penetration.
This percentage reduction is not applied to your target's total armor, but rather a part of it. Due to game balancing mechanics, a certain amount of a target's armor cannot be affected by the reduction. The maximum affected armor that can be removed is referred to as the "ArP effectiveness cap".
