In this video guide I will show you how to clear mission 5 without V's demons getting stalemated. This one is a lot easier on human difficulty. With that being said just pay attention to the demons health gauges during the fights and when they get about half way just don't use it until it recovers. The nightmare doesn't matter if it dies so don't worry about abusing him. The only fight that might be a pain is the boss. Since there might be a chance he can one hit your demons make sure that if he does just restart checkpoint. Just make sure to pay attention to the demons health and you will be fine. The achievement will pop at the end of the mission.
