I've got two artifacts: The Traitor's Die says Full INT with INT/DIS split when you level it up, except its actually STR/INT if you look at what the nodes do (even though they say INT/DIS on the descriptions). WTF? Same thing for The Damned Lute. I'd ask if there was any Quality Control that went on in the games, but I'd say the answer is a pretty resounding "No".
