Nioh

At the end of the chapter, a new boss awaits, the tactics against which are quite simple. You can get through the first half of the battle by throwing a talisman of laziness and a talisman of reduced defense at him (you can buff the weapon and eat a bunch of strength pills). Just run behind him and throw all your stamina at him. When half of his life is over, he will begin to summon flying red eyes. Run back some distance and shoot him with a cannon. Pretty basic. You may not even receive damage.
