Before you want to imbue a item from Charsi, simply save and exit in case she gives you something that's not-that good. Go to the window where they display the Diablo 2 save game file. Copy and paste the file so that you have 2 of same save games. Use the first save game and imbue the item you want. If it is a not-that good item, exit and duplicate the second save game then delete your FIRST one. This cheat allows you to duplicate again and again.
