Aeorian Robe

This floor length archaic looking robe is dark purple with black trim. It is lined with a light grey wool-like substance. It is unusually light and warm.

While attuned to this robe, the wearer can cast mage armor as an action, once a day. The spell ends if you don armor. This ability recharges on a long rest. 

While wearing robe, wearer has a +1 to Arcana checks

Fezal Alloreth dons his protective robe. Wandering these halls without any protection is dangerous. The robe shimmers for a sec as the arcane energy envelopes him. "There we go", he thinks to himself, all ready. He opens the door.....

Notes: Bonus: Arcana
