I got really lucky during the Jinana fight. I got low on HP and ended up using Heat's Vile Blade and that took up two sphere thingies and the turn would've been over if I hadn't finally beat her with that attack. Chances are she would've used Seraph Lore and wiped out my party if I didn't get lucky.

 

Void Expel is the key. Seraph lore is exple attack. If she can´t use it (or rather it doesn´t do any damage), rest is easy. Is good to have Dia on all chars too, you can use Angelic Grace (HP for all + Rakukaja effect). Not bad, but it will use up all press turns.

 

Oh, btw: you should obtain Chakra Walk (or Mana Walk) for all active characters. It´s good to have some SP all the time. And, if you already don´t do it, learn elemental path, which is character weak to (So learn fire path for Serph, Ice for Heat, etc.) At the end of path, there´s Resist skill, which void weakness of character.
