Electric Arc

You begin manipulating the air between two creatures you can see, charging it with magical energy. When you snap your fingers, several streaks of blue electricity spark and arc between the two targets, rising and dissipating, causing lightning damage.

You choose two creatures within range that are within 10 feet of each other. Each creature struck must make a Dexterity saving throw; if they're wearing metal armor, they make that save with disadvantage. Each Creature takes 3d8+3 damage, or half as much damage on a successful saving throw. The arcs of lightning ignite any flammable objects in the area between the targets 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 to all creatures increases by 1d8+1 for each spell slot level above 2nd.
