Then again, each battle can be made short by using Rikku's overdrive - Trio of 9999: Mix 1 Wing To Discovery, with a Lv 4 Key Sphere. each of which can be obtained before the battle with Flux.
Heh, I got 30 Wings of Discovery by opening three chests and winning the chocobo race at Remien Temple in the Calm Lands. I was able to do Trio of 9999 15 times. I played along just to see how hard the later bosses would be and things were so easy that I personally consider using that mix cheating. I mean, a Fire Gem which used to hit five times for about 600-700 per hit now did 9999 per hit dealing 50,000 hp damage in total. Ugh, Yunalesca didn't last five minutes with that, neither did any of the Sin Fins, Seymour Omnis or the rest of the bosses.
I wonder why they decided to include something like that in the game. It is the same with the KoTR materia in VII and the limit breaks in VIII, they are plain broken.
