I need some advice on how to beat the last boss in FFXIII?

[darthdevidem01]

Right as lestat said seraph crowns help

BUT I just used Vanille, light & Hope

Vanille cast poison which made everything easier

having all 3 on ravager build up stagger meter

having all 3 on medic really helps health

And by luck I beat him quickly...before he could use death on me.
