Artifacts - Best items class?

[jake21]

I've found pieces of "life ring" or similar (not sure of exact name). This is not quite the same as item set. How many of these pieces are there and what exactly do they do (or for that matter) how do you use them?

The specific piece I found this game was pair of shoes mentioned in this thread that give 4 int but last game I also found a couple of pieces (again can't remember the names of these bloody thing). Both this game and last game the items were found in Elron; land of elves.
