Cupid's Arrow

The next time you make a ranged weapon attack during the spell’s duration, the piece of ammunition or the weapon itself (if it is a thrown weapon), is imbued with a magical enchantment. Make the attack roll as normal. The target takes the weapon’s normal damage on a hit, but they do not experience any pain. Instead, the target must make a Wisdom saving throw or be subject to the effects of a Philter of Love (DMG 184).

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