This article explains how [[Armor calculation]] in [[Guild Wars]] works, offers some simple rules-of-thumb.

{{main|List of armor effects by category}}

Armor bonuses and penalties are divided into 3 main categories:

* '''Core armor''', consisting of:
** [[Basic armor]]
** [[Insignia]]
** [[Mysticism]]
** Base [[Shield]] armor
** [[Inscription]]s (actual inscriptions, not [[Inherent modifier|inherent mods]] that can be reproduced with inscriptions)

* '''Bonus armor''', consisting of:
** All other [[Upgrade component|weapon mods]]
** [[Inherent modifier|Inherent mods]], including [[Unique item|Unique (Green) item]] mods
** Non-skill [[effect]]s ([[Consumable]]s, [[Blessing]]s and [[Title (skill type)|Titles]])
** Almost all [[skill]]s, with the exception of those in the Special armor category
** Any penalties from [[Cracked Armor]]
** The penalty from [[Anniversary Shield "Curtain"]] in PvP

* '''Special armor''', consisting of:
** Bonuses: [["I Am Unstoppable!"]], [[Illusionary Weaponry]] and [[Mantra of Signets]]
** Penalties: [[Critical hit]]s, [[Barbed Arrows]], [[Healing Signet]], [[Shadowy Burden]] and the [[Flux]] effect [[Massive Damage]]

Before you read the rest of this guide, you may want to brush up on the following mechanics and bugs:

== Step-by-step calculations ==

Follow the steps below to calculate your effective armor rating:

=== Flow chart ===

[[File:Armor Calculation Flow Chart.png]]

=== Step 1: [[Armor calculation#Categories|Core armor]] ===

Add everything from the Core category.

=== Step 2: [[Armor calculation#Categories|Bonus armor]] ===

Calculate your ''net Bonus armor'' by adding all bonuses and subtracting all penalties from this category, including the penalty from Cracked Armor.

* If the net Bonus is 26 or above, add 25 armor or the highest flat bonus provided by a single effect (if higher than 25).
** This mechanic results in the bug where armor reduction effects will be ignored when a single effect higher than +25 exists and the net bonus is calculated to be 26 or above.
* If the net Bonus is 25 or lower, add that value.
* If the net Bonus is negative, it can only decrease your armor to 60, or to your Core armor, if that is lower than 60.

=== Step 3: [[Armor Penetration]] ===

[[Armor penetration]] reduces the armor by a percentage. For instance, an attack with 10% armor penetration on a target with an armor rating of 100 against that damage type will deal damage as if the target had an armor rating of 90 instead. Armor penetration follows the formula:

The table below shows armor effectiveness for various levels of Armor Penetration:

{|{{STDT|+=margin:0.25em auto;}}
|+ '''Effect of Armor Penetration'''
|- style="background:#ADA;"
! Armor Level !!0% Penetration !! 5% Penetration !! 10% Penetration !! 25% Penetration !! 50% Penetration
|- align="right"
|40||141%||146%||152%||168%||200%
|- align="right"
|50||119%||124%||130%||148%||183%
|- align="right"
|60||100%||105%||111%||130%||168%
|- align="right"
|70||84.1%||89.3%||94.9%||114%||154%
|- align="right"
|80||70.7%||75.8%||81.2%||100%||141%
|- align="right"
|90||59.5%||64.3%||69.5%||87.8%||130%
|- align="right"
|100||50%||54.5%||59.5%||77.1%||119%
|}

=== Step 4: [[Armor calculation#Categories|Special armor]] ===

Finally, add all the bonuses and subtract the penalties from the skills in the Special armor category. The result is your effective armor rating.

== Examples ==

To raise familiarity with Armor Calculation, here are a few examples of different situations.

=== Example 1 ===

A [[paragon]] with 9 [[Command]], max [[Basic armor|armor]] with [[Centurion's Insignia]], a [[Spear]] [[of Defense]] and a Command [[Forgotten Shield]], under the effects of [[Soldier's Fury]], [["I Am Unstoppable!"]] and [[Cracked Armor]], is hit with [[Lightning Orb]]. What is the effective armor rating of the paragon? By looking at the [[List of armor effects by category|list of armor effects by category]] and following the steps above, calculating this is pretty straightforward.

==== Step 1: Core armor ====

Add everything from the Core armor category:
* Basic armor: max paragon armor is ''80''
* Insignia: the Centurion's Insignia trigger under Soldier's Fury: ''10''
* Base Shield armor: the requirement for the Forgotten Shield is met: ''16''

Total Core armor: '''106'''

==== Step 2: Bonus armor ====

Add all bonuses and subtract all penalties from the Bonus armor category:
* Bonuses:
** Inherent mod from the Command Forgotten Shield (it triggers versus Lightning Orb's lightning damage): ''10''
** Of Defense mod from the Spear: ''5''
* Penalties:
** Soldier's Fury: ''20''
** Cracked Armor: ''20''

Net Bonus armor: '''–25'''

Because the net Bonus armor is lower than 26, add it to the Core armor: '''106 – 25 = 81'''

==== Step 3: Armor Penetration ====

Apply the proper percentage of Armor Penetration.

Lightning Orb has 25% Armor Penetration: '''81 × 0.75 = 60.75''', rounded to '''61'''

==== Step 4: Special armor ====

Finally, add the bonuses and subtract the penalties from the Special armor category:
* Bonuses:
** "I Am Unstoppable!": ''24''

Effective armor rating: '''85'''

=== Example 2 ===

A [[mesmer]] with 9 [[Inspiration Magic]], non-max armor with an armor rating of 30 with [[Sentry's Insignia]], a [[40/40]] set, under the effects of [[Elemental Resistance]] and [[Illusionary Weaponry]] (with 4 other Illusion skills on the skill bar), is hit with an arrow.

==== Step 1: Core armor ====

Add everything from the Core armor category:
* Basic armor: non-max armor, in this case ''30''
* Insignia: the Sentry's Insignia trigger because of the stance: ''10''

Total Core armor: '''40'''

==== Step 2: Bonus armor ====

Add all bonuses and subtract all penalties from the Bonus armor category:
* Penalties:
** Elemental Resistance at 9 Inspiration Magic has a penalty versus physical damage: ''17''

Net Bonus armor: '''–17'''

Because the net Bonus armor is lower than 26, add it to the Core armor: '''40 – 17 = 23'''

However, Bonus armor can only lower your armor to 60, or to your Core armor, if that is below 60. In this case, the Core armor is 40, and Bonus armor can only lower your armor to '''40'''

==== Step 3: Armor Penetration ====

Apply the proper percentage of Armor Penetration.

In this case, there is no Armor Penetration, so this step is skipped.

==== Step 4: Special armor ====

Finally, add the bonuses and subtract the penalties from the Special armor category:
* Bonuses:
** Illusionary Weaponry with 4 other Illusion skills: ''25''

Effective armor rating: '''65'''

=== Example 3 ===

An [[elementalist]] with 8 [[Earth Magic]], max armor with [[Blessed Insignia]], a Spear [[of Enchanting]] and a (13 armor, requirement 8) Strength Shield with the inscription [["Riders on the Storm"]], under the effects of [[Armor of Earth]] and [[Armor of Salvation (item effect)|Armor of Salvation]], is hit with Lightning Orb.

==== Step 1: Core armor ====

Add everything from the Core armor category:
* Basic armor: max elementalist armor is ''60''
* Insignia: the Blessed Insignia trigger under Armor of Earth: ''10''
* Inscription: "Riders on the Storm" triggers versus lightning damage: ''10''
* Base Shield armor: the requirement for the Strength Shield is not met: ''8''

Total Core armor: '''88'''

==== Step 2: Bonus armor ====

Add all bonuses and subtract all penalties from the Bonus armor category:
* Bonuses:
** Armor of Earth at 8 Earth Magic: ''43''
** Armor of Salvation: ''5''
* Penalties:
** Cracked Armor (like above, Lightning Orb inflicts Cracked Armor before doing its damage): ''20''

Net Bonus armor: '''28'''

Because the net Bonus armor is over 25, check whether the highest Bonus armor bonus is higher than 25. Armor of Earth is, with 43.

Adding that value to the Core armor gives '''131'''

==== Step 3: Armor Penetration ====

Apply the proper percentage of Armor Penetration.

Lightning Orb has 25% Armor Penetration: '''131 × 0.75 = 98.25''', rounded to '''98'''

==== Step 4: Special armor ====

Finally, add the bonuses and subtract the penalties from the Special armor category. None are applicable in this case.

Effective armor rating: '''98'''

== Notes ==

* The actual effective armor rating after calculation may be one lower than expected if Armor Penetration is involved, because its exact mechanics are unknown.
* Since the introduction of the [[Flux]] effect [[Massive Damage]], Special armor penalties (including the Flux effect) can lower your effective armor below 0.
