How can you beat this character?

1. He moves faster then anyone else
2. He runs through his summons and I can't
3. The camera turns away from him as soon as he runs making it impossible to target him for a rush attack
4. Can he be frozen?
5. This is with level 7 whirlwind and level 6 rush!
6. Can I use the DC mode and pile stuff in front of the entrances so he can't get in?
7. Can I spam my death blow to level 50 or something then return it to normal?
8. I'm on normal difficulty - is it possible to kill him on the easiest setting?
9. Can I spam it to a super stun arrow or something?
10. Death ray (yes, I'm frustrated)?

THIS is the type of battle that is destined to lower my feeling for a game big time - it's just plain ludicrous!
