I think I have to quit

This is a great game, but I'm stuck and don't see a way forward.
I'm in the Hall of Madness with Yveen and actually made it to Baretta, but cannot win. Yveen has little equipment and no items and I couldn't find anyplace to replenish so I could level her up. Baretta dies early in the fight every time. (I've tried Drama, etc., but they don't help.)
I'm playing the hard option, as I always do. I can keep Yveen alive (through guarding and healing) in a fight with one, but not with two.
Is there any way I can go forward, or is this it?
