Thorn Grasp

You create thorny tendrils in the space of a creature within range. Make a ranged spell attack against the creature. On a hit, the tendrils twine around the target, which takes 1d8 piercing damage and can't regain hit points until the start of your next turn.

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