I finally beaten final fantasy XIII, I did had trouble fighting barthandelus , but then manages to defeat, barely surviving his ultima attack that causes massive damage. then having trouble against ophan in his 1st form, took me 7 tries just figure what I've done wrong. what I was not doing is that I needed fang in the party cause her high damage. also attack ophan is stupid cause he has an attack that'll cause an instant KO but this only effects on the Leader so. I switched to ravage then uses fire ability cause I'm wielding the helter-shelter then keep healing myself and my party as Hope does the samething as Fang is in sentenal. then gone to ophan 2nd form which is alot easier than his 1st. but he cast doom on you. so gonna have to act fast. took me 2 minutes and got a 5 star rating. then game has ended! man I'm good. Still trying upgrade weapons to it's fullest potential. so goona do so. comment ,etc and thanks.
