Iron Reflexes
Keystone
KeystoneIronReflexes passive skill icon.png
Converts all Evasion Rating to Armour. Dexterity provides no bonus to Evasion Rating [1]
Why should I dodge blows that I do not fear?

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.

Even with zero evasion rating, the minimum chance to evade is 5%. Taking Arrow Dancing along with the Iron Reflexes keystone results in a 6.5% chance to evade projectile attacks and 3.5% chance to evade melee attacks. The overriding exception is the Unwavering Stance keystone, which will set chance to evade to 0% regardless.


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.
