Windup

ᚹᛁᚾᛞᚢᛈ

You pull your arm back, covering it in a large spinning mass of rock, and aim a devastating punch at a creature or object you can see within range. Make a melee spell attack against it: on a hit, you strike it with full force and it takes 6d10 bludgeoning damage. On a miss, some of the rock still manages a glancing blow, dealing 2d10 bludgeoning damage instead.

If you have not moved during this turn, you can choose to charge the blow up further before unleashing it. If you do, your speed is 0 until the end of the current turn, and the spell deals an additional 1d10 damage, regardless of hit or miss.
