You have Darkvision with a range of 60 feet.

You have Proficiency in the Perception skill. You also have Advantage on Wisdom (Survival) checks you make in dim light or darkness.

When you take the Attack action on your turn, you can replace one of your attacks with a terrible screech in a 15-foot Emanation. Each creature in that area must make a Constitution saving throw (DC 8 plus your Constitution modifier and Proficiency Bonus). On a failed save, a creature takes 1d8 thunder damage and is Deafened for 1 minute. At the end of each of its turns, the target repeats the save, ending the condition on itself on a success. On a successful save, a creature takes half as much damage. This damage increases by 1d8 when you reach character levels 5 (2d8), 11 (3d8), and 17 (4d8).

You can use this Sonic Blast a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Short or Long Rest.

When you reach character level 5, you can channel nocturnal energy to give your wings extra strength. As a Bonus Action, you spread your leathery wings on your back for 10 minutes or until you relinquish this strength (no action required) or have the Incapacitated condition. During that time, you have a Fly Speed equal to your Speed. Once you use this trait, you can't use it again until you finish a Long Rest.
