Steel Sword (Superior): Against The Elements In An Skellig

Set sail for the northern isle of An Skellig, docking your boat at either the Bay of Winds or Urialla Harbor. The treasure you seek is along the pathways that twist and turn through the hilly wood and heather to the northwest of the island. Follow the path north to a trio of abandoned huts.

Just beyond these abandoned huts is a trio of bandits you can face. Afterwards, head to the cliff edge and rock shrine. Ignore the offerings in front of the shrine; the chest is tucked away on the other side of the shrine rock.
