Thunderburst

A burst of thunder streaks forward from the caster in a 50 foot line that is 10 feet wide in a direction they choose. Each creature in the line must make a Constitution saving throw. A creature takes 6D6 thunder damage on a failed save and is stunned until the end of your next turn. On a successful save they are not stunned and take half as much damage, constructs or creatures made of metal, stone or other brittle materials make this save at disadvantage. At higher levels the damage of the spell is increased by 1D6 per spell level.
