So I've completed FFX-2 god knows how many times. I figured I'd play a brand new game from scratch and try to 100% straight away instead of just completing it multiple times. So I got to Chapter 2, right towards the end of the Chapter in Infiltrate Bevelle! As soon as I get inside, after taking the elevator down (I've tried this three times) and there's a battle I can't escape, (Oversoul Flan Blanco and I think it was an Oversoul Archaeothyris) But because I'm stupid, I didn't bother to level up previously because I wasn't expecting this battle and it seems like it's just been set out for me, so I have to do it. I'm level 21 and they just basically kill me within seconds, I don't get the chance to do anything and because I can't backtrack or board the airship, I'm just completely stuck and not sure what to do. Because it's just a new game I don't have all the dresspheres either. I own Yuna, Rikku and Paine's special dresspheres, but I don't even have the time to change to them within the battle. The dresspheres I've been using, I was just varying between warrior, gunner and white mage. I'm not really sure how to go about doing this battle. Any ideas?
