Arcane Bombardment

You mark a point within range to be struck by a cataclysmic missile.

When the spell ends, each creature within 15 ft. of a point you choose within range must make a Dexterity saving throw with disadvantage, taking 3d10 piercing damage and 3d10 fire damage on a failure, or half as much damage on a success. In addition, all creatures within 20 ft. of the point you choose much make a Constitution saving throw, taking 3d8 thunder damage on a failure, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, both the piercing and fire damage increase by 1d10 per level of spell slot above 5th.
