Chapter 17: Martyr's Chamber

First, remove the corpse from the clamp-like machine in the middle of the room. Then use the amulet to decay the iron holding the chains of the other corpse on the wall. Grapple the corpse and pull it towards the clamp machine then release to lock it in place.

Now pick up the other corpse and enter the newly opened doorway. Place the corpse down then operate the machine to lift you up. Pick up the corpse again and stand near the edge of the ledge until the camera pans down to the pressure plate below. Throw the corpse there to lift the metal box that you can use as foothold to reach the next ledge. Once there, go to the right to find a Gorgon Eye.

Martyr Chamber Gorgon Eye

After the conversation with the scribe, continue through the hallway to the left, then jump to the room below. Take out all enemies then pull the large chunk of meat(?) until it's under the hanging ramp above.

Follow the path and climb up the ladder then exit. Continue along until you trigger a scene. Complete the basic QTE and the Chapter will be complete.
