Lightning Arrow

3rd-Level Evocation
Casting Time: 1 bonus action, taken immediately after hitting or missing a target with a ranged weapon attack
Range: Self
Components: VS
Duration: Instantaneous

As your attack hits or misses the target, the weapon or ammunition you're using transforms into a lightning bolt. If you hit the target, it takes an extra 4d8 lightning damage from the attack. but on a miss, it still takes half of this extra damage. Then, the each creature within 10 feet of the target makes a Dexterity saving throw, taking 4d8 Lightning damage on a failed save or half as much damage on a successful one.
The spell ends early if you cast it again or cast another smite spell, such as shackling smite or ensnaring strike.
