Stun Baton

Weapon (mace), rare

This slender rod has an insulated grip and a conductive tip. All bludgeoning damage dealt by an active stun baton is nonlethal, while the electrical charge can be either nonlethal or lethal. By activating a control in the handle as a part of an attack action, you can switch the attack between a nonlethal jolt (bludgeoning damage that automatically stabilizes a target if you reduce them to 0 hit points) and a lethal shock (damage type is changed to lightning). On a critical hit, a target must succeed at a DC 14 Constitution saving throw or be stunned for 1 round. When it’s not activated, a stun baton functions as a mace. A character who is proficient with simple melee weapons is proficient with a stun baton.
