Yeah, I believe Barnabus' mace was the best weapon I found in the game. I hadn't read that I had to give in his weapon, so suddenly when I finished that quest I found myself without a main hand. I was pretty dismayed, had to buy one from the smith at the harbour. I found a couple of good 1h weapons, one of them legendary (bought it in High Hall I think), but I do think I still would've used Barnabus' at the end of the game if I'd had it. Too many weapons with intelligence requirements/bonuses. Very annoying for purebred melee'ers.
