Bonus armor

Bonus armor is the armor value shown in green numbers with a plus on the left, right below the white armor number on a unit`s statistics. Whenever an item or skill shows a +armor value, e.g. Blade Mail (+6 Armor), it increases the bonus armor of the affected unit. The difference between main and bonus armor is that illusions only benefit from main armor, although their HUD still shows the bonus armor just like on other heroes, to make them less obvious to the enemy.
