- Go forward through the open doorway ahead of you and down the corridor and to the next balcony.
- 3 Shanks will drop from beyond the balcony into the area below.
- 2 Barricade Servitors will appear in this area.
- This will open into another room with a barrier, but this is the final one.
- In this final room, you will encounter Selkis, the Obstructor.
- Selkis will move first to the back portion of the room.
- While it is there, a number of Exploder Shanks will drop from the ceiling.
- Destroying those will have more Shanks come into the room.
- Selkis will jump toward where you entered the room after that.
- Follow it as it moves around the room and destroy it.
