Aura of Light

You release a strong light that damages creatures in a short range. You shed bright light in 10 ft radius and dim light for another 10ft. Creatures starting their turn within the 10 ft of bright light must make a constitution saving throw, taking 2d6 radiant damage on a failure. On a success, the creature takes no damage.

When cast with spells slots higher than 1st-level, you increase the damage by 1d6.
