Swift Stars

You create an array of three stars that fire forth with bright radiance. Each star hits a creature of your choice that you can see within range. When a star hits it deals 2d6 + 3 radiant damage to the target. The stars strike in quick succession one after another, you can direct them to hit one creature or several. If a creature is hit with three or more stars they must make a Constitution saving throw, or become blinded until the end of their next turn.

Using a Higher-Level Spell Slot. The spell creates one more star for each spell slot level above 1.
