Loathsome Limbs: Whenever the zombie takes at least 5 bludgeoning or slashing damage at one time, roll a d20 to determine what else happens to it:   1-8: One leg is severed from the zombie if it has any legs left. 9-16: One arm is severed if the zombie has any arms left. 17-20: The zombie is decapitated.   If the zombie is reduced to 0 hit points, all parts of it die. Until then, a severed part acts on the zombie's initiative and has its own action and movement. A severed part has 8 AC. Any damage it takes is subtracted from the zombie's hit points. A severed leg is unable to attack and has a speed of 5 feet. A severed arm has a speed of 5 feet and can make one claw attack on its turn, with disadvantage. Each time a zombie loses an arm, it loses a claw attack. If the head is severed, the zombie loses its bite attack and its body is blinded unless the head can see it. The severed head has a movement speed of 0ft. It can make a bite attack, but only against a target in its space. The zombie's speed is halved if it's missing a leg. If it loses both legs, it falls prone. If it loses both arms, something something I'll finish this later.
