Thosha I've found what may be a failure in the playthrough. In Chapter 2 Yarra's Route, it states:
"Orgasmic Rogue 2 defensive (both have to hit first try), 3 piercing attacks (4.5-5k HP)
Ghenalese Orc Mage 1 aggressive, 1 defensive, 1 aggressive
Arclentian Warlord Huge Health Potion, 2 defensive, 3 piercing, 1 defensive, 4 piercing attacks
Rodak Elite Lose"
Even with hits exactly when needed, it auto-fails. The Arclentian Warlord kills you before you can use the Huge Health Potion. You are too slow before he strikes and you never get to the round with the Rodak Elite.
