Thunderous Roar

You unleash a thunderous word with immense power that detonates around you. Each creature within 20 feet of you must make a Constitution saving throw or take 6d6 thunder damage and be pushed 10 feet away from you. If a creature succeeds on the saving throw, it takes half damage and is not pushed.

At Higher Levels: When you cast this spell using a 4th-level spell slot or higher, the damage increases by 1d6 for each spell slot above 3rd level.
