Nope, using two handed on both my physical attackers and shields on my two mages. My mages also have Angelic Ward and Damage Dispersal abilities though which helps a lot. I alternated between defaulting and then all out attacking with lots of Braves after he had used a turn in advance. Didn't take too long to beat that way.Have you equipped shields on all your characters to soften his blows ? I am at the same level but the only strategy I've found is to hit and default alternatively each turn.
