Destructive Impact

You cause an orb of fire and molten rock to come crashing down from the sky, targeting a point on the ground you can see within range. You must be outdoors to cast this spell. When you cast this spell, the fiery orb materializes as an easily visible point in the sky that casts a 5-foot radius shadow centered on the point you targeted. At the start of your next turn, the orb lands at that point and explodes. Each creature in a 40-foot diameter sphere centered on that point must make a Dexterity saving throw. The sphere spreads around corners. A creature within a 10-foot diameter of the point of impact takes 7d8 fire damage and 3d8 bludgeoning damage on a failed save, or half as much damage on a successful one. Creatures within the remaining area only take the fire damage component of the blast, rather than taking both fire and bludgeoning damage. This spell deals twice that amount of damage to objects and structures within the area, and ignites flammable objects that aren’t being worn or carried.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the fire damage increases by 1d8 for each slot level above 5th.
