Since the game was updated and a lot of things (uniques which boost specific tower, pre and afix, itempwr is not shown anymore...) has changed. This is definitely the most interesting site in the wiki. The question everyone that played a lot in the beta would ask is: "how to drop better items".
There are some Theory but they dont have any proof. - Do i have to upgrade my Amor, Relics and stuff to find better ones? - If i have a Legendary item which has 4 stats and mystic item with 3 stats and the total sum of the 4 stats is bigger ... does this mean the legendary is better in itempwr then the mystic?
