Master Digler:
We must have this amulet to attract the opponents who are interested in Enuma Elish. Fortunately, it can be obtained through other means...
One way is to defeat the Demon Halisha , who is located within the four great cemeteries. You must form a party to enter.
If that proves too difficult, defeat the followers of Halisha at the Memorials of the Lords. By doing so, you can earn "tickets." Once you have acquired over 700 tickets, Halisha himself will appear. By the way, the creatures you must face are the Grave Scarab, Scavenger Scarab, Grave Ant, Scavenger Ant, Shrine Knight and Stander.
