Thundercrack

With the innate magic flowing through you, you bend the weave of magic and release a concentrated blast of sound. Make a ranged spell attack against a target in range. If it hits, the target takes 10d6 thunder damage and immediately is deafened until the end of their next turn.

This spell cannot crit. Instead, on a dice roll of 20, add 4d6 damage dice.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 2d6 for each slot level above 4th.
