Is that new with the Mistlands update? I'm sure I used frostner on bonemass not too long ago, but pre-Mistlands. It worked very well, of course.

Yes some items from the Merchant are locked by boss kills. Thunderstone thing after Elder, Ymnir Flesh after Bonemass and a new mistland related item after Yagluth.
