Nothing gets past you folks! You correctly identified the black magic Artificing item as the Poppet. It's made with, among other things, a fur tuft of the intended victim. As previously mentioned, you really don't want anyone to have these from you. See today's teaser video for the reason why, and why it's worth paying a bounty hunter to fetch one from anyone who annoys you too much... And don't worry, poppets have durability, so if someone does get one of these made with your fur, and you can't steal it from them, they'll wear it out eventually.
