Note: If you look at the information section of an item you will see a bunch of numbers associated with each tier. The higher the number the faster it tiers. All other things equal, when you buy an item from auctions it pays to look at these values before picking which one to bid on. I have a corrosive chip at tier level 9 right now because it has crazy high tier values. Unfortunately, who wants to put an enhancer on a corrosive I chip You all probably knew that, but I figured there might be someone out that that could benefit from this advice.
