The Artificial Eye in The Puppet's Casket is located inside the large grandfather clock safe in the Headmaster's Study, found in the West Wing of St. Gideon's Orphanage. Unlocking it requires a three-part combination—27-09-18—which you assemble by finding three hidden Memento Dolls. Securing this item is not optional; it is the only way to unlock the "Insight" mechanic, access the final area, and achieve the game's True Ending.
This guide provides the most direct, spoiler-free path to obtaining the Artificial Eye, detailing the location of every required component, the solutions to each puzzle, and strategies for any enemies you'll encounter along the way. Without it, you are locked into the bleak "Bad Ending," so consider this questline mandatory.
What is the Artificial Eye and Why Do You Need It?
The Artificial Eye of the Watcher is more than just a key. It's a permanent upgrade that fundamentally changes how you perceive the game world. Once equipped, it grants you the Insight ability, which allows you to see the invisible: ethereal pathways, hidden lore inscriptions on walls, and the glowing weak points on otherwise invulnerable enemies. The world of St. Gideon's is built in layers, and Insight is the tool that peels back the veil.
Its primary function is to grant access to the Orrery of Souls, the final boss arena where you confront the Marionette Master. The door to this chamber is sealed by a spectral lock that only becomes visible and interactable when you have Insight active. Attempting to approach the end of the game without the eye will leave you facing a literal dead end, unable to proceed.
Furthermore, the eye is the sole determinant of the game's ending. Defeating the final boss without the eye's power results in the "Bad Ending," where the cycle of torment within the orphanage continues. Only by using the Insight gained from the eye to expose the Marionette Master's true weakness can you achieve the "True Ending" and finally bring peace to the tormented spirits of St. Gideon's.
The Complete Walkthrough: Finding the Artificial Eye
This quest can be broken down into three main phases: acquiring the key to the Headmaster's Study, finding the three-part combination for the safe, and finally, opening the safe itself. We recommend having at least the Silvered Hatchet and a few bottles of Laudanum before beginning, as you will face resistance.
Step 1: Obtain the Headmaster's Key from the Bell Tower
Your first objective is the Headmaster's Key, which is kept in the orphanage's Bell Tower. The tower is accessible from the second-floor balcony that connects the East and West Wings, just past the Music Room.
- Navigate to the Bell Tower: From the Grand Foyer, take the western staircase to the second floor. Proceed through the long gallery, avoiding the Whispering Dolls that patrol the hall. The door to the exterior balcony is at the far end. Cross the crumbling stone walkway to enter the Bell Tower.
- Solve the Bell Puzzle: Inside, you'll find three large bells and a faded plaque on the wall. The plaque reads: "Sorrow's toll, then Joy's reply, then Silence's lonely cry." This is the puzzle's only clue. You must ring the bells in the correct sequence.
- The Solution: The solution corresponds to the small carvings at the base of each bell's rope. The bell with the crying face is "Sorrow." The bell with the smiling face is "Joy." The bell with no face is "Silence." Ring the bells in this order: Crying Face, Smiling Face, Blank Face.
Upon ringing the final bell, a small compartment will open at the base of the central bell stand, revealing the tarnished brass Headmaster's Key. Pick it up and retrace your steps. The Headmaster's Study is located on the first floor of the West Wing, a large oaken door marked with the Headmaster's crest.
Step 2: Locate the Three Memento Dolls for the Combination
The grandfather clock safe requires a three-digit combination. Each digit is inscribed on the back of a small, porcelain Memento Doll hidden in a different section of the orphanage. You must find all three. The order doesn't matter, but this route is the most efficient.
The Crying Child Doll (Infirmary)
The first doll is in the derelict Infirmary on the first floor of the East Wing. This area is filled with crawling enemies known as "Bedside Crawlers," so move carefully. Proceed to the back of the main ward, past the overturned gurneys, to a small surgical theater. On the wall behind the operating table, one of the bricks looks discolored. Interact with it to reveal a hidden alcove. Inside, you'll find The Crying Child Doll. Turn it over to find the first number: 27.
The Grieving Mother Doll (Chapel)
Next, head to the Chapel, located just off the main Courtyard. The doll is on the main altar, but it's protected by a pressure-plate puzzle tied to the candles on either side. A clue is visible in the large stained-glass window above the altar, which depicts three saints holding candles of different colors: red, blue, and white.
To solve the puzzle, you must light the three corresponding candles on the altar in the order they appear from left to right in the window. The correct sequence is: Blue Candle, White Candle, Red Candle. Lighting them in this order will retract the metal grate on the altar. Claim The Grieving Mother Doll and inspect its back for the second number: 09.
The Silent Father Doll (Boiler Room)
The final doll is the most dangerous to acquire. It's located in the basement Boiler Room, which is guarded by a formidable mini-boss: The Stoke-Keeper. This hulking, furnace-hearted automaton is slow but hits incredibly hard. Its weak point is the glowing red core in its chest, which is only exposed immediately after it performs its ground-slam attack. Dodge the slam, get in two or three hits with the Silvered Hatchet, and back away. Repeat this process, and it will fall.
Once The Stoke-Keeper is defeated, it will drop the Boiler Room Key. Use this to open the locked maintenance office in the corner of the room. The Silent Father Doll is sitting on the desk inside. The final number is on its back: 18.
Step 3: Crack the Grandfather Clock Safe
With the Headmaster's Key and the full combination (27-09-18), it's time to open the safe. Return to the West Wing and use the key to enter the Headmaster's Study. The room is dominated by a massive, ornate grandfather clock.
This clock is the safe. Interact with its face. You'll see you can rotate the large hand to select numbers on the clock face. The numbers you need correspond to the minutes, not the hours. You must input the three parts of the combination you discovered.
- Rotate the hand to the 27-minute mark and press interact.
- Rotate the hand to the 09-minute mark and press interact.
- Rotate the hand to the 18-minute mark and press interact.
A heavy clunk will echo through the room. The base of the grandfather clock will swing open, revealing a velvet-lined compartment. Inside rests the Artificial Eye of the Watcher. Take it. A short cutscene will play, and the item will be permanently added to your key items, with the Insight ability now passively active.
Using the Artificial Eye: The "Insight" Mechanic
You don't need to equip the Artificial Eye in a traditional sense; its power is always with you once acquired. When you are near a hidden object, your screen's edges will subtly shimmer with a faint, blue-white light, and a low hum will be audible. This is your cue that Insight is revealing something.
This mechanic is essential for the latter half of the game. It reveals previously invisible spectral bridges in the library, allows you to read lore-critical messages scrawled in unseen ink, and, most importantly, highlights the four spectral chains that anchor the Marionette Master during the final boss fight. Without Insight, these chains are invisible and indestructible, making the boss impossible to defeat.
What If You Miss the Artificial Eye?
There is a point of no return. If you proceed into the upper levels of the central Spire and initiate the final confrontation with the Marionette Master without the Artificial Eye in your possession, you are permanently locked out of the True Ending. The game will allow you to fight a simplified version of the boss, but you will be unable to break its control over the orphanage.
Upon defeating this lesser version, you will receive the "Bad Ending," titled "The Cycle Continues," where your character becomes another puppet trapped within St. Gideon's walls. The credits roll, and your save file will be marked with a puppet icon, indicating the incomplete ending. To get the True Ending, you would need to load an earlier save or start a new game entirely. Do not enter the Orrery of Souls without the eye.
Frequently Asked Questions
Can you get the Artificial Eye after beating the game? No. The game has a definitive point of no return before the final boss encounter. The Artificial Eye must be found before you confront the Marionette Master to achieve the True Ending.
Is the safe combination the same for every playthrough? Yes, the combination 27-09-18 is fixed and does not change on subsequent playthroughs or different difficulty settings. The locations of the Memento Dolls also remain the same.
What's the best weapon to use against the Stoke-Keeper? The Silvered Hatchet, found in a shed in the Gardens area, is highly effective. Its faster swing speed allows you to land more hits on the Stoke-Keeper's exposed core compared to the standard Rusty Pipe.
Does the Insight mechanic use any resources? No, Insight is a passive ability that is always active once you acquire the Artificial Eye. It does not consume health, stamina, or any other resource.
