I got an idea for a backpiece transmutation stone. I have seen some awsome backpiece skinns on gw2 and so far at each release there has been added a new back piece skin . Just like a bag slot expansion you buy with gems and you get slots to put extra bags. But on this slot you will be able to put a back piece skin like holografic wings and roxs quiver and you may change
your back piece as you please. There are alot of cool backpieces out there and i want them all. but its a horror that i got the awsome flower and tentacle bacpieces on my bank and i cant use them each the transmutation stone could cost like 800gems and if you want to expand your collection that would cost you onother 200. and only the apperance will change not the stats
