I plan on playing (first playthrough) with a sword in my right hand, and a spell in left. As you all probably know, I won't be able to block this way. I was just wondering, If I was facing magically resistant enemies, and found myself with little use for the spell hand, or just wanted to nix it, is there any way I could stop using the spell, so I could block with the sword? Or do I either have to have both hands equipped or none. This way, If I felt like spicing up combat, I could get rid of the spell and start blocking.
P.S.: We really should be able to block while dual wielding/spellswording.
