Dak's Falling Stars

You summon spectral meteorites to fall in a 20-foot radius cylinder within range. Each creature must make a dexterity saving throw, taking 1d8 radiant damage for each level of the spell on a failed saving throw or half as much on a success. In addition, each creature who fails the saving throw is coated in radiant starlight. For the duration of the spell, they shed bright light to a distance of 5 feet and dim light to 10 feet. They cannot benefit from being invisible, and attacks made against them deal an additional 1d8 radiant damage.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage of the ongoing effect increases by 1d8 radiant damage for every two levels above 4th.
