The tiger boss is a really hard boss to beat but there is a pattern you can do to easily defeat him. When he starts to run around the room is the only time you can hurt him. Before he starts line up and just before he hits you take a hit at him. Sometimes you can even hit him two or three times. Later in the battle he jumps up and rams you. When he does that, jump at him and hit him with your sword. He should be pretty easy if you do this.
