My way to enchant:
I buy 3 wepons and some scrolls.
I make the first wepon 3 and after i start to enchant the others.
After the others 2 are +1 or 2 i start enchant the wepon +3 and so until i will remain with only 1 wepon. I deposite on wh i buy again 3 wepons and start do the same after i got some wepons +++ i get them out of wh and i echant them with a lot of pain!
Voila!
