Bixby's Blast

A blast of blue light streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, it takes 1d8 force damage, and if the target is a Large or smaller creature, it is pushed back 5 feet.

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