There are a couple in occlo and around but you may be better off just posting a list of what you are looking for.
I have high end spined horned and barbed at my vendor in skara island. It is the only house on the island. Between the bank and the moon gate.
I recommend Larlochs small tower in Skara or Gideons Large Marble south of Trinsic in the Jura Peninsula also a small stone North West of Northern entrance of Vesper. Good luck n welcome to the Bod Game bud!
