Iron Reflexes

The Iron Reflexes keystone passive skill gives the following effects:

• Converts all Evasion Rating to Armour

This adds the player's evasion rating (after bonuses) to armour. Because it is a conversion effect, armour bonuses are applied to both evasion and armour as described in the following formula [1]:

Armour = Evasion * (1 + DexterityBonus + EvasionBonus + ArmourBonus)
       + Armour  * (1 + ArmourBonus)

Even with zero evasion rating, the minimum chance to evade is 5%. Taking the Arrow Dodging 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%.
