Auran Thunder

Mimicking a thunderstorm, explosion, roar, or other deafening noise you have previously heard, you use your action to force each creature besides yourself within 30 feet of you to make a Constitution saving throw (DC 8 + your proficiency bonus + your Charisma modifier). A target automatically succeeds on the save if it can’t hear you. On a failed save, a target takes thunder damage equal to 1d6 + your level and becomes deafened for 1 minute. On a successful save, the target takes half as much damage, and is not deafened.

Once you use this ability, you can’t do so again until you finish a short or long rest.
