Crown of Stars

Seven star-like motes of light orbit your head. As a bonus action, send one mote toward one creature or object within 120 ft. Make a ranged power attack. On a hit, the target takes 4d12 radiant damage. The effect ends when the last mote is expended. While four or more motes remain, you shed bright light in a 30-ft. radius; with one to three, dim light.
