I'm planning on doing Lute's scenario next. I'm doing some training with him in my current playthrough but I was thinking of changing him to be a supportive mage with the backpack and some heavy guns for damage when needed. I immediately thought of Rune magic for buffs but Arcane magic could be good too. Has anyone used Lute like this before? If so, which magic schools did you give him?
