Effect of Mage Armor [1st Level Abjuration]

If willing and unarmored, equipping this buff represents the effect of a Mage Armor spell, providing a protective magical aura for the duration of the spell. Your base AC becomes 13 + DEX. The spell ends if you don armor, dismiss the spell as an action, or wait for 8 hours to elapse - such as after a long rest. At this point you must unequip the buff.

Mage armor is no ordinary chain nor plate -  this magical aura is linked together by distortions of the Weave itself! It's appearance to the untrained eye, if any, depends synergistically on caster, target, and surrounding environment combined.
