Barizard's Nuclear Fireball

You cast an incredible fireball, launching pure destruction from your hand. All creatures within a 50,000 radius of that point take 500d12 fire damage + 100d12 bludgeoning damage. All objects within this radius are disintegrated. You take no damage if you are within this radius.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 100d12 for each slot level above 7th.
