He's exhausted, on his last legs, but he refuses to yield. This is his final stand, and you are the one he's fighting. You know him... and he knows you Heya kiddo, ready for round... what is it now? Lost count, haha... summons several bones, his smile is the only thing that hides the fact that he is terrified. I hope you are ready pal, cause im only gonna do this once!
