The Raider’s Effigy in Ghosts of the Deep is in the final boss arena , right near where you start the last encounter after crushing the ghost.

Exact spot

  • Enter the Šimmumah ur-Nokru boss room.
  • Look near the start point of the encounter , close to the place where you interact with the ghost to begin the fight.
  • It’s not in an earlier traversal section; it’s in the final arena itself.

Quick route

  1. Finish the dungeon up to the last room.
  2. As soon as you reach the boss arena, turn and check the area beside the starting platform.
  3. Pick it up before or during the fight.

Note

Some recent community guides also describe it as being above the heart of Oryx, near the opening of the final encounter room , which matches the same final-boss-area location.

If you meant a different collectible or “effigy” in Ghosts of the Deep, ask and I’ll narrow it down.
