Electrical Pulse

In the first turn, you choose up to six targets, and you make a ranged spell attack on each target. On a hit, the target takes 2d6 lightning damage. If you concentration on this spell is still not broken at the start of the second turn, you can use your action to create a stroke of lightning forming a line 100 feet long and 5 feet wide blast out from you in a direction of your choice. A creature takes 2d6 lightning damage per number of targets selected in the first turn, and it can't take reactions until the start of its next turn on a failed save. On a successful save, the target takes half as much damage and suffers none of the spell's other effects.

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