NOTE: If this video seems less bright to you than the others, you're right. Turns out my Dazzle's settings were screwed up, so I messed around with them some to get them back to normal.

I could've just linked to Garland's video - but that wouldn't have been very completionist of me, now would it?

Nonetheless, the strategy is once again carbon copy. The ability to customize doesn't really help you defend against Cross Cleave's 2,000+ damage, so the only solution is to kill Flux before he can use it... Or more adequately put, to push him into his next phase before he can use it. I had more luck with Flux' single-target attacks than Garland did, as he never targeted Rikku with anything that could kill her. She had a customized SOS Haste in case he would, but it evidently wasn't nescessary.
