i found out a cheat you can do. just drag any item you want click options and click the item in the options on the red backround and you will have all the things it gives you. keep repeating this process and you will be unstopable. PLZ KEEP THIS INFO ALIVE!!!
if you re-spec then youl lose all the points you got from doing it.
