- Grab the red orb from the previous step and place it on the spawn map (hanging on the wall).
- Activate the Kronorium and chase the ghost bird back to the prison.
-
The location of where the bird goes may vary. You will need to use the Spectral Shield to see the bird, but there are several locations including.
Note: On the 4th bird, you can only see the bird in Zombie Blood. Listen out for the bird or the Warden crying to locate the area of the bird. Use the number 8-7-2 on the number generator in the Citadel Tunnels to obtain the Zombie Blood. Instead of the shield, throw your Hell's Retriever/Redeemer at the bird and it will drop the Kronorium which you can then pick up.
