Arm Burst

You warp your outstretched arm to temporary increase in length and lash out toward a creature you can see within range. Make a melee spell attack against the target. On a hit, the target takes 1d6 bludgeoning damage, and is pushed back 5 feet.

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