Well damn, I was planning to have him be a dual wielder in the first place. Guess I'll have to change my plans a little. Maybe have him wield a rapier or something instead of the two short swords I was intending to use. Yeah, that kinda fits his Duelist style, actually.

You can have him dual wield, just add that (within sense) to once of his abilities. The first one seems to be the most appropriate for that, but fur it to make some sense plus look cooler and balance the addition of two-weapon fighting, you could add the note that he loses his stacks of her fails to land an attack with each hand, alternating between them, in addition of losing the stacks when he changes targets.

This feels like a much more interesting alternative for me.
