I'm planning on turning J'zargo into a Spell-Sword, I'm just wondering if he'll use a sword and his magic? If he doesn't use both a Sword and his own magic will he duel wield a staff and a sword?

I've already got his gear ready (Master Robes of Destruction, Ring of Magicka, Amulet of Magicka, enchanted Wolf Boots and Gauntlets, Silver Circlet of Destruction and an enchanted Daedric Sword)
