Concept art isnt a very good gauge for how stuff will end up being, gameplay-wise. And I was referring more to whether staves will be an actual weapon that you smash people with, or a spell casting kind of deal.
And for either case, I wonder what skill, if any, they will be a part of?
Well, the weapon skills are One Handed and Two Handed. I don't see why they can't be both with perks relating to the different kinds. Assuming they can be used as a blunt weapon. I mean, all weapon "types" fall under both. There are One Handed swords, and Two Handed swords. Don't see why Staves should be any different. :shrug: as was pointed out by Sleign we do have a screenshot of One Handed magical staves at the least.
As for the question at hand, I'll be using a Dagger if they make them and stealth as awesome as they claim. If not I'll fall back to Longsword. For my off-hand I will be using spells to aid my stealth. I'll also use a bow to stealthily pick off targets and range.
Oh and, Duel Shields FTW! That was the first thing I thought of when they revealed duel wielding.
