The hardest boss so far!!!

I don't think you can remove the DOOM status unfortunately :/

Check and make sure that you don't have any STAGGER LOCK weapons equipped, as I just realised I did and it took FOREVER to get him to stagger! Then I just blasted him with: Lightning/Fang/Hope and used a combination of Relentless Assault, Delta Attack, Mystic Tower, Combat Clinic. As soon as he casts DOOM on ya, you kinda have to go hard with Relentless Assault and try and beat him down as fast as you can!
