I performed the Dead Woods Brutality in a different way today. I smashed my opponents face with the three branch in the second round, then I didn't hit him when I was swinging on the three. Then the bastard knocked me out in Round 2. I tought it was over but I throw the piece of wood at him anyway and I performed the Brutality. So maybe you don't have to hit him with interactibles in the final round, you can do it any time. And if we can kill with Blanche, I bet we can do it with the Monk and the Kove's Dead Body. Every Stage has throwable stuff so let's experiment!
