Thunderbrand

You choose a creature you can see within range and brand it with a mark of swirling energy. The next time this creature takes damage before the spell ends, it must make a Constitution saving throw. On a failed save, the creature is deafened until the beginning of its next turn and takes 1d8 thunder damage, as a blast of thunderous energy erupts from the brand. The blast can be heard from 100 feet away. Whether the target succeeds or fails the save, this spell ends.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
