Barrage of Blades

You attack a single target within the range, of your choice. Wind and force come from yourself to send a flurry of slashes. The target must make a dexterity saving throw against your spell attack DC, and if they succeed they take half damage. On a failed save, the target takes 4d4 magical slashing damage.

This spell does an additional 1d4 slashing damage for each slot used above 1st.
