So I'm down to the final few missions that I need to complete, and this one seems to baffle me, i don't know if i just need to keep leveling up my characters or what. Neo ochu seems to insta kill me everytime it's screech move comes around. I usually use Lightning/Sazh/Vanille for my battle team, lightning maining com, Sazh maining Syn/Rav, and Vanille maining Rav/Sab/Med. any tips or strategies?
