Unstoppable Axe

Weapon (battleaxe), legendary (requires attunement)

This double-bladed battle axe has a hickory haft and a silver pommel inscribed with arcane runes. When you hit with an attack using this magic weapon, the target takes an extra 1d8 slashing damage.

When you hit a creature or a wooden object with the axe, you can release the haft and the axe hovers in place, continuing to attack the target on its own. The axe uses your attack roll and ability score modifier to damage rolls and makes one attack on each of your turns.

If the target moves away, the axe follows and continues to attack, moving with a flying speed of 60 feet. The axe continues to attack until the target is dead or destroyed, the target is more than 60 feet away from the axe, or you grasp the haft again. A wish spell can also stop the axe from attacking.
