The next time you make a ranged weapon attack during the spell's
duration, the weapons ammunition, or the weapon itself if it's a thrown
weapon, transforms into a bolt of lightning. Make the attack roll as
normal. The target takes 4d8 lightning damage on a hit, or half as much
damage on a miss, instead of the weapon's normal damage.

Whether you hit or miss, each creature within 10 feet of the target must
make a Dexterity saving throw. Each of these creatures takes 2d8
lightning damage on a failed save, or half as much damage on a
successful one.

The piece of ammunition or weapon then returns to its normal form.

\textbf{At Higher Levels:} When you cast this spell using a spell slot
of 4th level or higher, the damage for both effects of the spell
increases by 1d8 for each slot level above 3rd.
