A bronze arrow that has a simple, angular design; though it has shapes on one end vaguely reminiscent of fletching, it is not notched, and therefore cannot be fired from a bow.
You can use a bonus action to toss this magic arrow into the air and speak the command word. When you do so, the arrow begins to hover.
While the arrow hovers, you can use an action to cause it to fly up to 80 feet without moving more than 40 feet away from you and make up to four ranged attacks. The arrow can move through hostile creature's spaces, and can make these attacks only on creatures that share a space with it. The arrow uses your ranged attack roll; on a hit, its attacks deal piercing damage equal to 1d12 + your Dexterity modifier.
The arrow ceases to hover if you grasp it or move more than 40 feet away from it.
Proficiency with a Dart allows you to add your proficiency bonus to the attack roll for any attack you make with it.
