Thunder Blast

A blast of air so fast that it makes a rumbling sound, shoots out toward a creature within range. Make a ranged spell attack against the target. On a hit, it takes 1d6 thunder damage, and gets pushed back 5ft.

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