DFFOO GL#46 KUJA EX-BATTLE LVL 80 (KUJA, SETZER, YUNA) 30.8K SCORE
After trying so many combination (Yuna+Kuja+others), decided to use synergy character. Setzer is really useful for delaying the boss turn (need 35 CP) and freeze joker the boss. Yuna is good for erasing the debuff (need 15 CP). Kuja for Damage dealer (well my Kuja cannot be considered as DPS, since he still at 0 artifact with standard 1700ish ATK w/o Synergy)
Friend Support is Sazh for additional Buff, coz i couldnt found Cloud for launch/paralysis. It turns out to be a quite good move to bring Sazh Friend. I switched Yuna with Sazh, and buff Setzer + Kuja just before summoning Ifrit.
Will try other team mix combination, maybe Li Ti Ko can also crush the Boss. In my opinion, This EX Battle need team combination that is quite speedy or have some kind of turn manipulation (either turn delay or paralysis).
