He's tough, no doubt of that. I died several times. But I got used to his tactics, I learned how to avoid his major damage, and I figured out that he's not THAT bad. I would maybe be willing to help you beat him some time, send me a friend request (IGN Skouros)
In P1 just dont go near him. When he charges up his speed dash, you have to time your dodge just right. Too early and he re-targets and you get hit anyway, too late and you're too late to avoid the damage.
In P2 you have to kill his mirrors no matter where they are. If you hit him that is bonus damage, but make sure you're just hitting everything. Mirrors deal full damage so its best to take them out as well.
Make sure you kill as many of his mirrors on the ledges as possible. If you get lucky and hit him he comes down immediately and does not launch his swords (which is pretty deadly and hard to dodge).
In P3 if he floats up too close to you, RUN. He's probably doing his ground slam which will hit you even behind a pillar. If you're far enough, get behind the pillar and it will not hit you. If he does his float up and launches projectiles, again, pillar humping is plenty to avoid that.
I thought it was a pretty decently tuned fight. It seems like it would be challenging no matter what kind of weapon you have, or your skill level, but I can see if you're using a particularly difficult weapon to use against him + you're not the most skilled gamer (I know I am not, I readily admit that) it could be rough. Don't give up, when you beat him it will make it worth every hour!
