Celestial Incendiary Rain

You call down a barrage of fiery orbs from the heavens, showering a 20-foot-radius sphere centered on a point you choose within range. Each creature in that area must make a Dexterity saving throw. On a failed save, a creature takes 5d6 fire damage and is ignited, taking an additional 1d6 fire damage at the start of its next turn. On a successful save, the creature takes half damage and is not ignited.

Additional Details:

The fiery orbs are imbued with celestial energy, creating a stunning visual display as they streak through the sky before detonating in a blaze of flames. The area becomes a smoldering battlefield, and the intense heat lingers, creating a hazardous environment for those caught in the aftermath; becoming difficult terrain. Imposing disadvantage on those who try to cross the rubble. Use this spell to turn the tide of battle, laying waste to your foes while leaving a lasting impression of devastation.
