Multiple Threats: Victim is simultaneously, but independently, attacked by Attacker and Villain, who are equally culpable. Each is trying to kill Victim. Victim can disable Attacker by inflicting 10 units of harm on him. This will also deter Villain. Victim can also disable Villain by inflicting 20 units of harm on him. This will also deter Attacker.
