Cruddles Blade

Choose a creature that you can see within range. You create a circular saw blade shaped plane of force that hovers above that target until the spell ends, regardless of where (or how) the target moves. When the blade appears, you make a melee spell attack against the target creature. On a hit, the target takes 3d10 force damage. On a miss, the target takes half damage. Whenever the creature uses an action, repeat the attack. When the spell ends, repeat the attack.
