Recommend HP is 30000+
Need lots of Damage cuts, Heals, and Dispels.
To get past 50%, at least 3 Typhoon summon to clear Bahamut's charge is required in the party.
To get past 10%, being able to achieve 100% cut without summon is required (FLB Uno, Phalanx + Reflect, etc.). Nirvana and Fif also works.
