Armor

Armor is an attribute shared by all units. It reduces the amount of physical damage a unit takes, but can also increase the amount of damage a unit takes. The amount of damage a unit takes gets reduced if its armor value is positive, and increased if the armor value is negative. Armor is increased by Agility, certain spells and when you obtain items that increase armor.

Damage Reduction
Each point of armor reduces incoming physical damage. The formula used to determine the amount of damage reduced is as follows:
 * Damage Reduction = ( 0.06 * armor ) / (1 + 0.06 * armor)
