[edit] Description

Armor reduces damage taken from non-magical sources.

[edit] Equation

Damage Reduction = ([armor]*0.06)/(1+0.06*[armor])

There are many items and skills that grant additional armor.

Every point of agility gives 0.14 armor.

Here is a chart of damage reduction per point of armor. The damage reduction diminishes as armor increases; however, the effective hp increase you get does not. Every point of armor adds 6% of your max hp to your effective hp. The formula for effective HP is EHP = HP/(1-damage reduction) or EHP = HP (1 + 0.06*Armor)
