973 shares so far. Time for some more codes Answering some of the questions above: Regarding stones, they are used when your item reaches its highest upgrade level. Stones increase the level higher but its better to save them till u get good tier4 or higher(if available) items. As for higest tier level, tier3 is not highest. I am already carrying a tier4 set. I think there is a tier5 out there as well basd on the level patterns, but cant confirm.
