Archduke of Hell Azurael's Curse of a Thousand Hellish Blades

You hurl a thousand hellish blades at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1000d20 fire damage. A flammable object hit by this spell is incinerated, and its ashes are transported to a random place in the 9 hells.

Cantrip Upgrade. The damage increases by 1d20 when you reach levels 5 (1001d20), 11 (1002d20), and 17 (1003d20).
