Celestial Burst

You shoot a comet of cosmic light at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 radiant damage. If the target was an object, it takes no damage and instead emits bright light in a 30 foot radius until the end of your next turn.

The spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
