I wondered if I can.

I now carry no weapons, no armor, no enchanted items, nothing except for those “quest” items that can't be dropped. I don't equip or use any of those. So it's just my character in his underwear (sort of a caveman look) with max difficulty, dead is dead of course. So far, it's a very successful and interesting experiment.

“It isn't hard to do.”

Mage? Not too hard to do. A bit more difficult, I'd say, for a non-magic character using only fists and avoidance.

It was a little harder at max difficulty because magic damage is one sixth of normal.
