Easy experience and items
Create a Sorceress, then max out her Firewall. Trade some items for a good Tarnhelm, some ChaceGuards, and other +% to Magic Find items. You Sorceress should be at about level 45. Then, go to Channel Cows/Cowz and wait for someone to make a game. Join that game and Firewall all the cows. Your experience will increase and you will get unique items. Do not duel or do anything dangerous with this sorceress, as you will get killed.
Get any item
Use the following trick to get almost any desiered item. Go to the person in your highest Act that gambles (for exampel, Gheed or Jamella). Go to gamble. A list of good items will appear. If you do not see anything desirable, exit, then go to gamble again. There will be a new list of items for sale. Repeat the process until you have found what you want.
