Mage Arrow

Weapon (arrow), uncommon

When you fire this arrow from a bow at a target within its normal range, you don't make an attack roll for the attack. Instead, the arrow immediately splinters apart into 1d4 + 4 darts of magical force, as if by the magic missile spell. The darts all strike the target of the attack. The arrow is then destroyed, before it reaches a target.

Other types of magic ammunition of this kind exist, such as mage bolts meant for a crossbow, though arrows are most common.
