What your going to have to do is blind him.

The way to do that is this run around the arena till you come upon steps it's not going to look like steps cause the camera is far back, go up the steps run the wall the boss is going to punch at you but miss making an opening jump in the opening run up the wall.

Jump and grab on to a stick that is sticking outthen jump again and land on the platform you'll be able to see what to do after that. You'll jump and do the speed kill move and stab out one of his eyes.

After taking out his first eye theres another way back up but it's to a different platform run around the arena again and you'll see some more stairs go up them run the wall like before and the rest you should be able to see.

After putting both his eyes out just start attacking his legs. Hope that helped you.
