The throw range of your limb throw is 20 ft. If one of your legs are gone you get -1 to your dexterity. If both legs are gone you can’t move. If one of your arms are gone you get -1 to your strength. If both arms are gone you cannot attack except with unarmed attacks with your head or legs. If each limb has 1 8th of your health if the limb is killed it is gone until something heals it and you still get the disadvantages. When a limb is gone you have 1 8th of your maximum health removed until it comes back. On each of your turns if the limb is attached you can make a free attack action once for that limb. If the vorpal sword cuts your head off you are still alive and the head is still alive you can reattach your head.
