Dragon’s Roar

When you cast this spell, you emit an ear-splitting roar. All enemies within range that can hear the roar must make a Constitution saving throw. A creature takes 12d6 thunder damage on a failed save and is stunned until the end of its next turn. On a success they take half the damage and the creature does not suffer the stunned condition. In addition, all allies within range gain 20 temporary hit points, and gain advantage on the next attack roll, ability check, or saving throw they make during the next minute. The sound of this spell can be heard up to 900 feet away (or farther with a successful Wisdom (Perception) check as determined by your DM).
