. . . "Armor penetration (sometimes abbreviated ArP or called armor pen) is a number typically appearing on items that indicates the amount of armor ignored by an attack. It is a modifier that directly decreases the value of the armor of your target in combat time. Unlike Sunder Armor and Expose Armor which require active application, ArP items are passive. Some abilities, enchantments, items, and spells can contribute by adding armor penetration. ArP can be found as both abilities (ex. Sunder Armor), or as passive statistical upgrades found on equipment pieces (ex. Season 3 PvP armor). Armor penetration reduces the amount of armor that your target has against melee attacks. ArP is unique in that the more ArP you have, the greater the increase in damage becomes. Armor penetration is sometimes confused with spell penetration, even though they are calculated and function differently. Armor penetration is not a very recent stat. It has been seen in Serrated Blades since patch 1.10. Since itemization introduction of Arena Set 3, Blizzard has been popularizing the use of this modifier even into Image:Wrath-Logo-Small.PNG."@el . . . . . "Consider the following situation: a level 20 elementalist with 15 air magic uses Lightning Strike against a warrior wearing Gladiator's Armor (and not wielding a shield). Lightning strike has 25% armor penetration and the warrior has 80 AL versus elemental damage, which results in an effective 60 AL (80 * (1 - 0.25)). Against an effective 80 AL, lightning strike would have dealt 35 damage, but armor penetration will increase the damage to 501. This is roughly a 43% increase.

"We are always looking for ways to improve how player stats work. Our long-term plan is to simplify statistics and provide a more clear understanding of their effects on healing and damage dealing. For example, Spell Power will no longer be its own statistic, and Intellect will provide its benefits instead. We also plan to make Spirit the definitive mana-regeneration statistic, in which case we would remove the mana-per-5-seconds stat from gear. Confusing stats like defense and armor penetration will likely go away. Of course, existing items will be updated to reflect these changes. We're also adding a new stat called Mastery, which ties into a character's existing talents and will grant a unique function for each class. A rogue, for example, might gain an extra combo point through the Mastery stat."@en . . "is a champion statistic that reduces the effectiveness of a target's armor.
