Thindersnap

You audibly snap at a creature within range, sending a visible focused sonic wave at it. Make a ranged spell attack against the target. On a hit, the target takes 1d8 thunder damage. You can't miss objects with this spell that aren't being worn or carried.

On a critical hit with this cantrip, you roll triple the damage dice, instead of double.

At 5th level (2d8), 11th level (3d8), and 17th level (4d8)
