Armour is a rating that measures a character's physical damage mitigation. Every 12 points of Armour blocks up to 1 physical damage per hit. The absolute amount of damage blocked gets closer to the maximum the more damage the hit does; however, the proportion of damage blocked decreases.
Armour rating can be increased by wearing equipment, taking certain passive skills, using spells such as Module Error: Too many skills found with q_where = skill.active_skill_name="Molten Shell". Please choose only one of the following ids:
GravicusMoltenShell - Base duration is 10.00 seconds, Deals (143-2698) to (214-4048) Fire Damage, Shields break after (752-4460) total Damage is prevented, (4352-19367) additional Armour (page)

+1500 to ArmourRequires Level 27Right click to drink. Can only hold charges while in belt. Refills as you kill monsters..
Supposedly the most armour monsters have in the game is about 930.[1][better source needed]
Mechanics
Damage reduction from armour only reduces physical damage taken. Elemental damage and damage-over-time are not affected.
The amount of damage reduction is a function of armour rating and the damage taken. Damage reduction is capped at 90%.
Damage Reduction Factor = Armour / ( Armour + (12 * Damage) )
For example, if you have 1200 armour rating this chart indicates how much damage will be reduced by:
File:Damage reduction chart.png The vertical axis is damage reduction percent. The bottom axis is original damage.
Equivalently:
Net Damage = Raw Damage2 / (Raw Damage + Armour / 12) Defense Factor = Raw Damage / Net Damage = 1 + Armour / (12 * Raw Damage) = (1 + sqrt(1 + Armour / (Net Damage * 3))) / 2
Therefore we can conclude:
- If raw damage is much less than Armour / 12, raw damage has a near-quadratic effect on net damage. Equivalently, in this regime raw damage has a near-linear effect on net DPS if the raw DPS is held constant.
- If raw damage is much greater than Armour / 12, raw damage has a near-linear effect on net damage. Equivalently, in this regime raw damage has little effect on net DPS if the raw DPS is held constant.
- Against attacks of a fixed raw damage, armour has a linear effect on the number of attacks it takes to deplete a certain amount of hit points.
Another way of looking at it is in terms of absolute damage reduction:
Absolute damage reduction = Armour / 12 * Raw Damage / (Raw Damage + Armour / 12)
So damage from attacks is reduced by up to 1 per 12 points of Armour, which means that the supposed monster Armour cap of 930 blocks up to 77.5 damage per attack. Note that as raw damage increases, the damage blocked per attack increases, but the proportion of damage blocked decreases.
Passives
There are passive skill nodes that grant additional evasion or a combination of bonuses including evasion.
Armour
These passives increase armour rating by a percentage.
In the case of Iron Reflexes, armour is increased by an amount equal to total evasion. In exchange, evasion is reduced to 0.
Armour are a number of small passive skills that grant increased armour rating. All the passive skills share the same name, but have different values on increasing the armour rating.
Moreover, one of the passive skill node also grants flat armour rating.

Iron Reflexes is a keystone passive skill that removes all evasion rating and converts it to armour. It removes the bonus to evasion rating that dexterity inherently grants.
Mechanics
Conversion Formulae
The final Armour value is calculated with the following formula: [1][2]
Final Armour = Flat AR * (1 + [total #% increased/reduced AR]) * (More/Less AR modifiers) + Flat EV * (1 + [total #% increased/reduced AR or EV]) * (More/Less AR modifiers) * (More/Less EV modifiers)
where:
- EV = "Evasion Rating"
- AR = "Armour"
- Flat EV = Sum of Evasion Rating from Equipped Items (e.g. Body Armour, Shield) and other sources of additional Evasion Rating (e.g. Grace)
- Flat AR = Sum of Armour from Equipped Items (e.g. Body Armour, Shield) and other sources of additional Evasion Rating (e.g. Determination)
- More/Less modifiers from different sources (e.g. Determination vs Basalt Flask) are multiplicative with each other.
Modifiers which grant #% increased Evasion Rating and Armour (e.g. Bravery) or #% increased Global Defences (e.g. Skin of the LoyalSkin of the Loyal

This item can be transformed with a Blessing of Chayula) only apply to base values one time. For example, taking Bravery would increase flat ER by 24%, which would then be converted directly into the final Armour. It does not then apply 24% increased Armour, as the flat ER was already affected by that modifier.
When factoring modifiers which apply to specific equipment slots such as While a Pinnacle Atlas Boss is in your Presence, (67-70)% increased Armour from Equipped Helmet and GlovesArmourFromHelmetGlovesEldritchImplicitPinnaclePresence6
Eater of Worlds
While a Pinnacle Atlas Boss is in your Presence, (67-70)% increased Armour from Equipped Helmet and Gloves, each source of flat AR/EV should be calculated separately, then summed at the end. These modifiers are additive with other increases and reductions.

Summary
With Iron Reflexes:
- #% increased Evasion Rating mods are applied to flat Evasion Rating only.
- #% increased Armour mods are applied to flat Armour and flat Evasion Rating.
- #% increased Evasion Rating and Armour mods get applied to flat Armour and flat Evasion Rating.
Therefore, the mods that provide the most significant benefits in conjunction with Iron Reflexes are those that increase Armour or both Evasion Rating and Armour.
Location
Iron Reflexes is located in the Southern part of the tree near the Duelist Section. It is a stand-alone keystone.

Miscellany
These passives are related to armour, but don't fit into any other category.
Maximum Chance to Dodge Spell Hits is 75% [1]
Acrobatics is a keystone passive skill that causes spell suppression modifiers to grant spell dodge chance instead, at half their value. Spell dodge prevents spell hits, and is capped at 75%.
Mechanics
The chance to dodge rolls independently per spell hit; it is not entropy-based like evasion. Spell dodge occurs before block and other damage mitigation.
Location
Acrobatics lies on the far right side of the skill tree across the Ranger's starting area.
