Your unwavering faith grants you wings.  As a bonus action you can sprout a pair of wings that grant you a 60 feet flying speed.  Attacks of opportunity against you are made with disadvantage while you have these wings.  They vanish at the start of your next turn, where you fall if nothing is holding you aloft.

You can create these wings a number of times equal to your proficiency bonus, and regain all expended uses after completing a long rest.
