As your attack hits or misses the target, the weapon or ammunition you’re using transforms into a lightning bolt. Instead of taking any damage or other effects from the attack, the target takes 4D8 Lightning damage on a hit or half as much damage on a miss. Each creature within 10 feet of the target then makes a DEX saving throw, taking 2D8 Lightning damage on a failed save or half as much damage on a successful one.
The weapon or ammunition then returns to its normal form.
Using a Higher-Level Spell Slot: The damage for both effects of the spell increases by 1D8 for each spell slot level above 3.
