Greetings;

I am trying to get this last trophy, and one of the artifacts I obtained, the Ebony Armor from that sacrifice quest I know I got but must have I sold it, which is stupid but it was awhile ago before I knew it was important. Do you need to actually have in your inventory 15 artifacts for this trophy to unlock? Or is the fact that I obtained the Armor enough even if I don't have it anymore?

Thanks!
