Celestial Sunburst Barrage

From the vault of the heavens, you summon a cataclysmic barrage of micro-novas—tiny, unstable stars born from the raw fury of the Upper Planes. These miniature suns streak downward like divine judgment, detonating across a wide area.

Choose a point you can see within range. A storm of 12 miniature novas rains down in a 60-foot-radius, 120-foot-high cylinder centered on that point. Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 10d6 fire damage and 10d6 force damage (half on a success).

The force of the impacts creates a brief gravity well: creatures that fail the save are also knocked prone and pulled 20 feet toward the center of the area. The ground within the area is scorched into blackened glass and ash for 1 hour afterward; it becomes difficult terrain, and any creature that ends its turn on the glass takes 2d6 fire damage.

Lore & Flavor: Legends say this spell was first gifted (or stolen) from the solar devas of the Plane of Radiance during the Dawn War. Some scholars believe repeated castings in the same region weaken the barrier between the Material Plane and the Positive Energy Plane, occasionally causing spontaneous radiant outbreaks or the spontaneous birth of fire elementals.
