Releasing the Ichor into the Aqueducts

After following the Bird Phantasms and repairing the Aqueducts, head back to the Domus Aurea and activate the Wheel device to release the Ichor.

This will start another sequence where you must hit the button prompts when they appear on screen.

Enter the Domus Aurea again at the end and prepare to face Boethius.

• Note that Co-Op mode will be disabled after this step, so make sure you are prepared!
