Thunderous Roar

You let out a thunderous roar in front of you, causing a huge burst of sound that blasting enemies and revitalizes teammates.

Each creature you choose within 30 feet of you must succeed on a a Strength saving throw, or take 2d10 thunder damage and be pushed back 10 feet on a failed save, or half as much damage on a successful one and not be pushed. Unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell's effect, and the spell emits a primalistic roar audible out to 300 feet. Each friendly creature you choose within 30 feet of you regains hit points equal to the level of the spell + your spellcasting ability modifier, provided that the creature can see or hear you. 

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10.
