You fling a condensed ball of colorful lights and sounds at a creature you can see within range. Make a ranged spell attack. On a hit, the target takes 1d6 thunder damage, and the target is distracted by the lights and sounds until the start of your next turn. While distracted, a creature must make a Constitution saving throw whenever it casts a spell that requires concentration. On a failed save, the creature can’t concentrate on that spell, losing concentration on it at the start of your next turn.

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
