I'm running an Embermage in the first act. He's carrying a staff d(two handed) and the only active spell is Magma Spear. When I use the right button, instead of seeing the blast of mana, I see him take a round-house swing with the staff, and only if he's right on top of the target. I think I saw the spell go off once or twice when I first started him, but never since them. Is this a problem with how I have the controls set, or what?
