Tweaked from 5eYou already know this as 5e Fireball — It's a Fireball scaled up to 9th level — same single point-and-detonate fire blast that spreads around corners and ignites objects, but with a 40-ft radius, a whopping 40d6, and it knocks failed saves prone.
Deal 40d6 fire damage (Dex half) to all creatures in a 40-foot-radius sphere and knock failures prone.

You expell a massive explosion at a point within range. Each creature in a 40-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 40d6 fire damage and is knocked prone on a failed save, or half as much damage on a successful one but remain standing.

The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.
