Armour
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
Molten Shell, and drinking a

.
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 basic passive skills that grants increased armour rating. All the passive skills shared the same name, but have different values on increasing the armour rating.
Moreover, one of the passive skill node also granted flat armour rating.

Iron Reflexes is a keystone passive skill that removes all evasion rating and converts it to armour rating. However, the increased evasion rating bonus from dexterity is not applied.
Mechanics
Conversion Formulae
The final armour is calculated with the following formula: [1][2]
Final Armour = Base Evasion * ( 1 + % increased Evasion Rating + % increased Armour + % increased Evasion Rating and Armour ) + Base Armour * ( 1 + % increased Armour + % increased Evasion Rating and Armour )
Bravery (which grants % increased Evasion Rating and Armour) and similar passive skills do not get included into % increased Evasion Rating nor % increased Armour. These are only included into % increased Evasion Rating and Armour.
% increased Evasion Rating does not get included into % increased Evasion Rating and Armour.
% increased Armour does not get included into % increased Evasion Rating and Armour.
Example
1000 Armour
1000 Evasion Rating
80% increased Armour from Armour and Steel Skin passive skills
40% increased Evasion Rating from Evasion passive skills
24% increased Evasion Rating and Armour from the Bravery passive
Final Armour = 1000 * ( 1 + 80% + 40% + 24% ) + 1000 * ( 1 + 80% + 24% ) Final Armour = 1000 * ( 1 + 0.80 + 0.40 + 0.24 ) + 1000 * ( 1 + 0.80 + 0.24 ) Final Armour = 1000 * 2.44 + 1000 * 2.04 Final Armour = 2440 + 2040 Final Armour = 4480
Summary
With Iron Reflexes:
- % Increased Evasion Rating mods are applied to base Evasion only.
- % Increased Armour mods are applied to base Armour and base Evasion.
- % Increased Evasion Rating and Armour mods get applied to base Armour and base Evasion.
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.
