That should be an ok (if bizarre) party - I think Mazzy has an amusing dialogue with Edwin where she threatens to kill him but it doesn't come to blows.
If you're playing with Sola then watch out for his encounters - if you're not used to Tactics difficulty then these will be
extremely tough. If you're playing a good party I would advise you to leave Bodhi-hunting in Chapter 6 until your characters are quite powerful
