The Will of the Gods

You bring the Gods' wrath as you emit a bright light around you in a 30ft radius. Creatures within range must make a DC 15 Constitution saving throw. On failure, any creature with an HP of 15 below are executed. Otherwise, they take 2d8 radiant damage. On success, creatures affected are blinded and take 1d10 radiant damage. After using this spell, you cannot use it again after 2 long rests.

At Higher levels: Add 1d8 damage on failure and 1d10 on success. Add 1 each spell level above the first. The threshold of the execution also grows 5 each spell level.
