Javelin of the Harpy Eagle
Weapon (javelin), rare (requires attunement)
This barbed javelin embeds itself into creatures and hinders their movement. A creature hit by this javelin has its speed reduced by 10 feet until the javelin is removed. While you are within 120 feet of the javelin and you can see it, you can use a bonus action to speak its command word, causing the javelin to viciously remove itself from the target and fly back to your open hand or to an unoccupied space at your feet. You can choose to remove the javelin as a part of the attack while wielding it in melee. Alternatively, any creature can remove the javelin with an action. When the javelin is removed, the barbs deal an additional 1d6 piercing damage to the creature.

Like the harpy eagle, this javelin flies true and makes quick work of the prey it seeks. No foe can escape its brutal talons.
