learn to counter his counter attack. He has only 3 ways to counter you. when his sword is on the bottom, it's his shield stance, which can be countered by buster. If he has his sword on his right or on top of his head, you need to dodge his attacks 3 times. That's because he rages, where his attack pattern changes. So you should save buster up his sword right before he rages so you have 12 seconds to damage him + buster at the end.
