I just think a metal medallion would resist being smashed… that is why I thought of melting it.
Shells will smash but do not think a medallion would ….. if you hit it with a hammer it would just flatten.
Agree- esp given Gold is one of the softest metals around.
Not sure how they could get them from the medallion per say, maybe they are able to find another portal to the wraiths world? Or trapping the wraith & then be able to transverse into the medallion.
