Wait, what makes for a 'Wits' based build?
High crit chance and crit damage builds have the highest damage output in the entire game. You aim for 100% crit chance on near to that and focus on skills that boost crit damage, e.g. Scoundrel and Two Handed. It is seriously overpowered - I was one shotting dudes in Arx in my last playthrough on Tactician even though I never managed to get my hands on a decent two hander throughout the latter half of the game.
