Just so you do not need to be searching for it here is the link. Basicly for this achievement you need to unlock all 18 armor pieces from raids. Why do I specify the raid part ? Well because the other armors does not count for this achievement. The reason why it is this way, it's beecause this achievement is one of the older ones, when we did not had legendary armors from pvp or wvw. I do know it's a small thing in a big game with not much significance. I just would like to know your oppinions . Should this achievement description be rewriten to mention just raid armor ? Should it be moved into raid armor achievement category to make sure its just for the raid armors ? Should we get more of these for pvp and wvw sets as well ? There are so many possibilities that even I can't think of right now but maybe you can 😉.
