medusa can really fuck your strategy with any girl because she REALLY like span her petrified bullshit
So any soul will get recked without luck
the only way reliable to beat her is with raw stats but no anybody own party of atk 35-40k to easily change her mode of raging to stun in each turn without skill
i can beat expert mode with luck, 27k atk thunder/light <,< but i lose sometimes because my andromeda or idra or nike get petrified again and again..... it over if she enter in rage and u don´t have any eidolon or hime to cure it
