Arm Burst (Dreamforge)

You cause fully grown fleshy arms to temporarily emerge from your outstretched arm that lash out toward a creature you can see within range. Make a melee spell attack against the target. You have advantage on the attack roll if the target is not wearing armor. On a hit, the target takes 1d6 bludgeoning damage, and is pushed back 5 feet.

Cantrip Upgrade. The damage increases by 1d6 when you reach levels 5 (2d6), 11 (3d6), and 17 (4d6).
