Embered Apocalypse

You unleash a storm of twilight fire across the land, reshaping both life and terrain.(500-foot-radius area within range)

• Each creature of your choice in the area must make a Dexterity saving throw. On a failed save, it takes 20d6 fire damage + 20d6 radiant damage, or half as much on a success.

• Structures, forests, and nonmagical terrain ignite, leaving the area scorched and barren.

• For 1d4 days afterward, the land glows faintly with emberlight, shedding dim illumination at night
