Return the bedroom photo, use the Agonal stone at Ivan's door, and beat Vitria by attacking tentacles to crack the mirror. Ivan has just been dragged away when you reach the symbol-sealed entrance above the Film School stairwell, and that is where the Tenebris Somnia Agonal Stone section starts. You'll need the premiere photograph for the bedroom drawer before you can follow him.
Where do you find the Agonal stone for Ivan's door?
Put the premiere photograph into the empty frame on the right bedside cabinet in the third-floor bedroom, then take the stone from the unlocked drawer.
Return to the bedroom
Go back to Ivan's apartment on Floor 3 and enter the bedroom. Stand beside the cabinet to the right of the bed, next to the purple curtains, and use the Photo from your inventory on the empty frame. The drawer comes unstuck.
Take the stone from the drawer
Collect the white Agonal stone, also called the Hexagonal Stone. The pickup displays a pale stone with a dark symbol. This is the item you need for the sealed entrance.
How do you open the Agonal stone door near Ivan?
Bring the stone back to the symbol-sealed door at the top of the Film School stairwell, speak to Sanguis, and unlock the entrance.
- Return to the hallway where Ivan was dragged away and follow the blood trail upstairs.
- Approach the sealed door. Sanguis is waiting beside it and joins Julia for the approach to Ivan.
- Finish the conversation and open the door with the stone. The stone disappears when the entrance opens.
Save just beyond the door. Then walk to the end of the hall and interact with the curtains to trigger the scene before Vitria's fight. Save first so you're ready for the battle that follows.
How do you beat the Vitria mirror boss?
Bait the opening monster's vertical attack, use the mirror to locate its hidden tentacle, then crack the mirror during the stun window and enter the portal.
Bait the opening attack and counter with the Pipe
Move close enough to draw out the vertical attack, then step back as it strikes. Hit with the Pipe during the opening and repeat. Waiting for that attack gives you a clear chance to counter instead of trading hits.
It can also charge a vertical strike or send tentacles diagonally in the direction it faces. Keep watching its windup rather than staying planted in front of it for extra swings.
Find the reflected tentacle and break the mirror
Once Vitria appears inside the mirror, direct attacks won't work while the red sigil protects the boss. Keep moving and dodging until an upright tentacle appears only in the reflection. Use its reflected position to find where to attack in your room, then strike it until the boss is stunned.
Switch your attacks to the stunned boss. The Revolver is the better choice for this window: the Pipe can take long enough for the boss to recover before you finish cracking that section. Keep attacking until the section cracks fully and a portal opens, then go through it.
Strike ground tentacles with reversed controls
Inside the mirror dimension, your controls are reversed. Keep moving until Vitria summons tentacles from the ground, then strike those tentacles until you're sent back outside.
Repeat the outside stun, mirror-breaking, and portal sequence until the entire mirror is cracked. More tentacles appear as the battle progresses, so keep repositioning between openings. One cracked section isn't the end of the fight.
Where do you go after defeating Vitria?
Speak to Sanguis to receive the Iron Key and the Lapis Fictus Pill, then unlock the door on the left.
Save in the next room, then take the north door into the Film Set. Interact with Ivan on the floor and let the scenes play out. This leads into Julia's Desiderium; follow that section before the later Sanguis corridor chase.
How do you survive the Sanguis corridor chase?
Bait Sanguis into breaking ordinary mannequin barriers, then time his lunge so the retracting blade impales him.
- When Sanguis transforms, start running east through the long hallway. Move clear when he lunges.
- If ordinary mannequins block the route, bait a lunge into them to break the obstruction. Watch for spike sections as you continue.
- At the retracting blade, draw his jump across its path just as the blade comes out. The successful trap leaves him impaled among the mannequins.
Sanguis cannot break red mannequins. Don't wait in front of a red barrier expecting his next lunge to clear it.
After the trap, head left through the black door at the end and go down the steps. Julia bandages her hand with the first aid kit. A short scene shows a ghost carrying another through the Floor 0 door; save at the nearby save point before continuing with the Forging the Aurifer walkthrough.
