Magical Weapons.. weee!
Yes, you can enchant weapons to make them even more fun and uber.. you need two things:
1) Mr. Forge Man. Available in Chapter 1 or 2.. somewhere in Neverwinter city itself.. so I forget which chapter that is. However, you don't get the really juicy weaponry/armor/etc at the forge until chapter 3 or 4. Make sure you save any diamonds, adamantite, iron wood that you come across. You'll really wish you had them later when you meet Mr. Forge Man (who will give you a book on what components/items are needed to get shit taken care of).
2) Components. Like I said.. see above. Some of the nifty weapons require either dragon blood or fairy dust as well. There is a forge in Neverwinter city as I mentioned before (which I think you need to ask for "special" inventory from some ogre store-owner guy to get access to?)
On baby: I'm going to bed now in anticipation of another super-fun day-plus of uncertainty, pain, monotony, boredom, and suffering (barring actual quick-arrival of Haylee into the world, anyway!)
Weeeeeeeeeeee!
Best,
