True Authority (requires attunement)

You must be attuned to a crook of the flock to attune to this weapon. The attunement ends if you are no longer attuned to the crook. While you are attuned to this weapon and holding it, your Charisma score increases by 4 and can exceed 20, but not 30. When you hit a beast with this weapon, the beast takes an extra 3d6 bludgeoning damage. For the purpose of this weapon, “beast” refers to any creature with the beast type. The flail also has 5 charges. When you reduce a humanoid to 0 hit points with an attack from this weapon, you can expend 1 charge. If you do so, the humanoid stabilizes, regains 1 hit point, and is charmed by you for 24 hours. While charmed in this way, the humanoid regards you as its trusted leader, but it otherwise retains its statistics and regains hit points as normal. If harmed by you or your companions, or commanded to do something contrary to its nature, the target ceases to be charmed in this way. The flail regains 1d4 + 1 expended charges daily at dawn.
