My method was this (and best to use one of each class in party for the whole game)
- Harrit, use a warrior and smash boxes
- Lysette
- Segrrit, again warrior to smash boxes
- Flissa
- Adan
- Minaeve
- Therrn
I have noticed a glitch when both using tactical camera, and not using it. (Note: I play on the PS3).
Sometimes you have to click twice on the person to actually save them. This is a pain when trying to save Adan and Minaeve. My suggestion is to save after saving Flissa in the tavern. That way you can redo it if you fail both.
