Iron Reflexes

Iron Reflexes is a keystone passive skill.

Iron Reflexes removes all evasion rating and converts it into armour.

Even with zero evasion rating, the minimum chance to evade is 5%. Taking the Ondar's Guile keystone along with Iron Reflexes gives the player a 10% chance to evade projectile attacks. The overriding exception to this is the Unwavering Stance keystone, which has the side effect of setting chance to evade to 0%.

Mechanics

Conversion Formulae

The final armour is calculated with the following formula:

Final Armour = Base Evasion * ( 1 + [total all % increases that apply to armour or to evasion] ) 
             + Base Armour  * ( 1 + [total all % increases that apply to armour] ) 

In other words:

Final Armour = Base Evasion * ( 1 + Armour% + Evasion% + "Armour and Evasion%" ) 
             + Base Armour  * ( 1 + Armour% +            "Armour and Evasion%" )

In other words:

 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 ) 

Leather and Steel (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 Leather and Steel 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 benefit in conjunction with Iron Reflexes are those that increase Armour or both Evasion Rating and Armour.
