Infestation

You cause mites, fleas, and other parasites to appear momentarily on one creature you can see within range. The target must succeed on a Constitution saving throw or take 1d6 piercing damage. If the target takes any of that damage, the target moves 5 feet in a random direction. Roll a d8 for the direction: 1, north; 2, northeast; 3, east; 4, southeast; 5, south; 6, southwest; 7, west; or 8, northwest.

The spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
