Avenging Angel

At 20th level, you can assume the form of an angelic avenger. Using your action, you undergo a transformation. For 1 hour, you gain the following benefits:

• Wings sprout from your back and grant you a flying speed of 60 feet.
• You emanate an aura of menace in a 30-foot radius. The first time any enemy creature enters the aura or starts its turn there during a battle, the creature must succeed on a Wisdom saving throw or become Frightened of you for 1 minute or until it takes any damage. Attack rolls against the Frightened creature have advantage.

Once you use this feature, you can't use it again until you finish a long rest.
