Rag = 3/5. Basically it comes down to whether if she focuses on my Heroic Spirit. Can't go too hard in the beginning without being able to stun her before her ougi. You have to be able to take out rage in 4 rounds of attacks. I don't apply my defense down debuffs in the beginning because she becomes raged if I do (45% down with Dark Amon and sniper).
And you need a lot of attack. I have a mono-black team, skill level 18, mostly assault weapons, and 3.8k attack on my grid. Otherwise, it's hard to imagine how someone does this. With Jean and a lot of heals? How much does she do with 50% attack down? Like 4k ougi and 1k autos? Maybe it would be easier if that's the case, but I certainly can't get that high (no sol T_T)
