If I could make one change to CBM magic items I'd increase the cost of this cursed (literally) item to 10 gems.
What about making it unpickable?
I wish; but we'd need IW to make the change. They did that for slave collars but I don't know if they didn't want to make the change for lychantropos' amulet or if it wasn't as much of a problem at a 10 gem cost (7 gems with a hammer of course).
(not to mention that the chances of amulet of the werewolf being picked up is 100% so even if you win a battle against a zmey with your army, you have to say bye bye to one of your mages (and that's just a nice side effect))
100%? Really? Because I dont think even artifacts have a 100% recovery rate?
