Mage Armor

Gives subject +4 AC bonus for 1 min./level (1 min per level is PnP style, DDO seems to be more like 5 minutes); Incorporeal creatures cannot bypass like normal armor.

The armor bonus for mage armor does not stack with other bonuses with the same name. For example, if a character has the following improvements:


 * +5 armor bonus (chainmail)
 * +4 armor bonus (mage armor spell)

His total armor bonus will be +5, not +9.

For this reason one should not cast mage armor on most medium and heavy armor wearers, unless you are fighting incorporeal foes.
