Perhaps... But I doubt it. Tactic don't help when the enemy pshyches up to 50 then unleashes hell on your character. But I did discover something. While defending against the darksteel at 50 tension, he only did 300 on jessicca, which is his normal damage without tension. So if I defend with jessicca and angelo, while using thunder thrust and executioner with the other 2, I may have a chance.
Good bye everyone, it's been fun!
