With a snap of your fingers, a clap of your hands, or a spoken word, you shape the vibrations to produce a booming crash in a 15-foot cone. Creatures in the area must succeed on a Constitution saving throw or take 1d6 thunder damage.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6). Upon reaching 11th level, the damage becomes vibrational.
