Click flag twice keys 1 2 and 3. This fight can be pretty hard and using the wrong combos to not deal enough damage in the 10 turn limit will result in a megidolaon (one shot kill).
First test, not done at all, currently at the third phase where joker begins to change to forms that allow weakness (1 more). The game wont progress from there for the time being. May be a while before its finished Currently in game: Standard 3 moves agi (light fire dmg) bufu (light ice dmg) and slash cut (light cut attack). fuuka can invoke oracle later in the fight on command, oracle is based off of persona 3 portable's rng for oracle. There is no "1 more" system in the first 2 rounds and there is no weakness, and you cannot crit him in the first rounds as well, after round 2 however joker can crit you with "primal force" (1 in 4 chance) for the first 1 more he can hit, once i have made the next rounds you should be able to crit and use the right elements for your own 1 more. Update log: 2026/06/04 -> phases up till 3 is complete with fuuka integration. Begining removal of redundant code.
