Hermit:
Now I shall teach you about the second test. The Archon of Halisha has the fifth Resonance Amulet. You must capture him in order to obtain the fifth Stone.
After doing so, you can commune with the Tablet of Vision that is northwest of the Wall of Argos.
Now I will tell you how to capture the Archon of Halisha.
He is often at the Imperial Tomb. Capture his followers on the northern side of the Wall of Argos, and he might come out.
My wait for the successor may yet be over. Go carefully, and good luck be with you.
