Cursed Sword Townie
You have a cursed sword you can try to kill someone with. If you hit scum then they will die and you can hit someone else with it. If you hit town then you and your target will die and the sword will be passed to a random townie who will lose his current role and become a cursed sword townie. If you don't use your sword you will die by the night (and you cant be protected from it).
Any roles that remove poison or curses will remove the sword.
You win with the town
