Game Guide by Amaya on Oct 19, 2026
To unlock Ending 2, "MAGNUM OPUS," kill at least one Relicta ghost near the end of the game with the Aurifer Knife. You don't need to kill every ghost; a single kill is enough to change the final boss and trigger the bad ending.

Obtain the Aurifer Knife
Progress through the main story until you reach the final Desiderium section. You must first obtain the Aurifer Knife to trigger Ending 2.
Once you have the knife, look for the nearby save point and save your game. This lets you return to this section if you want to unlock the other ending later.
Kill a Relicta Ghost
After obtaining the Aurifer Knife, you'll encounter Relicta ghosts along the route to the finale.
Find a ghost and attack it with the Aurifer Knife. Killing just one Relicta ghost unlocks Ending 2. You don't have to defeat every ghost you encounter.
Avoid using another weapon, as the ending condition specifically requires killing a Relicta with the Aurifer Knife.
Reach the Septimo Arte Building
After killing a Relicta ghost, continue along the route toward the final area.
Follow these steps:
- Continue through the Hotel doors until you return to the Studio Lobby.
- Leave the Studio Lobby and return to the apartment building hallway.
- Enter the rightmost door to reach the staircase.
- Climb the stairs to the third floor.
- Enter the third-floor apartment hallway and head all the way to the left.
- Enter the door with water leaking from underneath it.
- Continue left along the street until you reach the Septimo Arte building.
- Enter the building to reach the final area.
You can run past the remaining Relicta ghosts if you have already killed one with the Aurifer Knife. You don't need additional kills to unlock the ending.
Defeat Hermes
After entering the Septimo Arte building, continue through the final area until you reach the last boss encounter.
Because you killed at least one Relicta ghost with the Aurifer Knife, you'll face Hermes instead of Lacuna. Defeat Hermes to finish the game and unlock Ending 2, MAGNUM OPUS.

Final Thoughts
Getting the bad ending in Tenebris Somnia is simple: obtain the Aurifer Knife, kill at least one Relicta ghost with it, and complete the final section of the game. Save before making your choice so you can experience both endings without replaying the entire adventure.
