Dazing Bolt

A narrow bolt of bright lightning falls from the sky and blasts a point of your choice within range. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. Creatures wearing armor made of metal have disadvantage on this saving throw. On a failed save, a creature takes 3d6 lightning damage and is stunned until the start of your next turn. On a successful save, a creature takes half as much damage and isn't stunned.

The lightning ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
