Thunderclap and Flash

You create a burst of thunderous sound that can be heard up to 100 feet away and then 'flash' to any point up to 120 feet away that you can see. Each creature within 5 ft at your starting point and 15 ft at your ending point, other than you, must succeed on a Constitution saving throw. On a successful save take half 3d8 thunder damage. On a failed save take full 3d8 thunder damage.

(When cast at higher levels, flashing can have more than one end point and thunderclap causes more damage. Each spell level added to the casting adds 1 end point and 1d8 of damage. Max of 3 endpoints.)
