Acidulous Glaze

 You cause a wash of burning acid to form on one creature that you can see within range. The target must make a Constitution saving throw. On a failed save, the target takes 1d6 acid damage, and it is knocked prone.

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