Lightning bolt

VSM, self (100-foot line), instantaneous
A stroke of lightning forming a line of 100 feet
long and 5 feet wide blasts out from you in a direction you choose. Each creature in the line
must make a Dexterity saving throw. A creature
takes 8d6 lightning damage on a failed save, or
half as much damage on a successful one. The lightning ignites flammable objects in the area
that aren't being worn or carried.
