Pretty much what the guy above me said. You have it pretty much mindless till phase 5 because now you have things you have to worry about such as mountain busters, and bombs. If you get up to phase 5. You will have seen two of the three patterns he does. The last pattern he does he will always lead with it during phase 5. Is the 3 lines as a tank you run around the edge with the boss to the side that spawned last. The middle bombs will explode you run there and hit a cd for the incoming mountain buster.
