Mage armor is a set of magical protections that deflects and absorbs blows, functioning in a similar fashion to armor without impeding the use of magic.
Mage Armor requires a physical representation in order to have an effect. You must be wearing talismans or other clearly magical objects or symbols on 3 of the following areas: torso, head, upper arms, or forearms/hands.
You must have the Abjurer ability in order to benefit from Mage Armor.
While you are wearing Mage Armor, your maximum Hit Points are increased by +2.
You can cast spells and perform rituals normally while you are wearing Mage Armor.
Mage Armor does not block Cleave or Impale effects; if you are struck by one of these effects while wearing Mage Armor, you take the effect as you normally would if you were wearing no armor at all.
