Final Fantasy XIII Chapter 9 Final Boss HELP!!!

[VentusSearcher]

I finnaly beat it! What I did was used Lightning, Hope and Fang. I started by taking the puldrons and attelets out with diversity. Then when they were all gone I staggered with relentless asult, turning to bully to heal and cast debuffs and buffs. Then when Destrodo came I used combat clinic to heal really fast, then bring the stagger bar to 180 to make the attack lest effective with rellentlus assult.
The problem was that I needed to farm CP. I was really far behind because I skipped battles and barely got by in the game, and then it caught up to me.

Srry for the double post.
