The RNG is strong in this one...There are people who were lucky enough to get this achievement before getting the achievements for solving 20 of each artifact and unlucky ones that are still working on it after many, many solves. The slight advantage is you can trade your many  Restored Artifact for Archaeology fragments of other races. Of course, the best trade is for  Crate of Tol'vir Archaeology Fragments , for people still searching for  Crawling Claw or for  Scepter of Azj'Aqir . Also, the  Tol'vir Hieroglyphic are selling pretty good on the AH and they can drop from the crates.

It does grant the Seeker of Knowledge title and it is no walk in the park, the Lorewalkers Lodestones and Lorewalker Maps that brann sells come from start to finish (lodestone for getting around instantly, and map for whenever you finish either all the pandaren artifacts or mogu)

Be warned, it seems that the last pristine takes quiet a few solves, mine was the branding iron and i solved about 60 before i finaly got the final one, and for the first few i got them after 5... Good luck!

Awards the title "<Name>, Seeker of Knowledge" upon completion.
