Nice one, frodo2040.
Of the big ones I remember fighting Nelis with the GUI minimized and one or two teammates dead. Won in the end, but it was hard as I didn't remember who had how much health and how much PsP!
Still, first time around when I tried the academy, I lost quickly, and on the first win I think I had one or two teammates left. With Nelis it was easier on the first try, losing only two, i think (but that was a long time ago during TRPG2 beta testing stage!). After that, I never lost a teammate on the Nelis battle on any of the difficulties thanks to exploting her attacking preferences (ie with yellow orb and vengeance, go after Nelis with the Main, whilst keeping everyone else at a safer distance and ensuring that she only uses Fire Gate).
