Thunder Breath

You produce a deafening noise that blows the eardrums of all foes in a 30ft sphere this sheds a dim light on another 25ft. Each creature in that line must make a saving throw with a DC of 8 + your Constitution modifier + your proficiency bonus, taking 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. (This also produces a ringing in any allies in range)
