Ad Artelysia Stella

You raise a magical rod to the sky, channeling your inner celestial power to call down the stars themselves. When you cast this spell, you forcefully pull a meteroite towards yourself, causing the night sky above to blaze with radiant energy. Upon casting the spell, the meteor travels for one turn, and hits you at the end of your next turn.

All creatures within 500 feet of you must make a Constitution saving throw, including the caster themselves, but you get advantage on this save. If the spell DC of this spell is lower than 19 due to a low spellcasting ability, this spell's save DC becomes 19. Any creature that fails takes 10d10 radiant damage and an additional 5d10 fire damage. Creatures that succeeded the save take half as much radiant damage and does not take any fire damage. Then, all creatures except yourself must roll a d6, the number they roll becomes their level of exhaustion. Creatures that succeeded the Constitution save gains half as much exhaustion levels as they rolled (rounded down).
