Dragonbone Arrowhead LV.4

Usage affixed to a melee weapon or a ranged
weapon with the thrown trait. Activate 1 Action-Interact; Requirements Expert with the affixed
weapon. Until the end of the current turn, the
affixed weapon gains the thrown 20 feet weapon
trait, and when you make a thrown Strike with it,
it flies back to your hand after the Strike completes.
If your hands are full when the weapon returns,
it falls to the ground in your space.
