Loot Worth Keeping - Diablo 2
This page contains a complete list of all the Unique and Set Items that you should keep an eye out for in Diablo 2. What I liked to do while I was just starting out/getting back into Diablo 2 is tab over to this list after I found an item and use Ctrl + F to see if it is on the page. If it isn't then I know what I found was garbage, if it is on this page then I pay more attention to the item and the roll on it.
I put together this list using the webpage over at the Classic.Battle.net website (link provided) as well as information that other people provided online. For an additional comprehensive list of items (this time being ranked by tier) I recommend you check out the Unique and Set Items 'best of the best' page.
