Notes: why not add all 3 skills?

New page

[[Armor penetration]] (often abbreviated as '''AP''') is the amount of [[armor rating|armor]] that an [[attack]] or [[spell]] ignores when calculating [[damage]].

For example, an [[Air Magic]] spell that grants 25% armor penetration treats a foe with an [[armor rating]] of 80 as if it had only 60 armor, i.e. <code>80 - 25%*80</code>. This would cause approximately ~41% more damage to the target than otherwise, since the increase in damage is dependent on the base armor rating.

There are two different types of armor penetration: ''base armor penetration'' and ''bonus armor penetration''.

== Base armor penetration ==

''Base armor penetration'' is the [[Effect stacking|non-stackable]], fixed amount of penetration listed in a skill's description, e.g. "this attack has 20% armor penetration". If there is more than one source, only the highest value is used.

==Bonus armor penetration==
''Bonus armor penetration'' is an additional amount of armor penetration, such as "armor penetration +20%". These '''do''' stack (adding them together) and add to the largest base armor penetration.
* [[Sundering]] [[weapon upgrade]]s have a 10-20% chance to give attacks an additional 20% AP.
* [[Hornbow]]s have an additional 10% AP on their attacks.
* [[Judge's Insight]] gives an additional 20% to attacks.
* The blessing [[Warrior's Might]] grants an additional 10% AP to attacks.

==Notes==
The armor provided by [["I Am Unstoppable!"]], [[Illusionary Weaponry]] and [[Mantra of Signets]] is '''not reduced''' by armor penetration: it is '''only applied''' at the end of the [[armor calculation]]. As such, it is not counted in the [[effect stacking#Effect caps|bonus armor cap]] of +25.
{{anomaly|Armor Penetration does not simply subtract the listed percentage of armor, [[Talk:Armor_penetration#Armor_Penetration_is_not_a_simple_formula|sometimes it subtracts slightly more]]. The exact mechanics are unknown.}}
