Do you have to have all of the artifacts at once or does the game just count if you've beaten the missions? I sold my first artifact to a random store owner because it was a staff & I stupidly thought "A staff? Lol gtfo here, swords & bows for life!"
I mean I still think that way...just not for the artifacts. :P
