Armour Piercing (AP) is a value representing the weapon’s capacity to pierce through armour. AP is compared to the defender’s Armour in an Asymptotic Ratio 2.5. However, if the Armour Piercing value is higher than the opponent’s Armour value, the armour is considered as giving no protection at all and the victim suffers full damage. Some warriors use multiple weapons during the battle, like a sword in melee and a lance to charge. If this is the case, the letter "S" is used for secondary melee weapons, and the letter "R" for range weapons.
This value currently increases with levelling, but this is expected to change with the integration of equipment. The current formula used is:
Final WpD = Basic WpD X 1.029183Level (gains 33% every 10 levels)
