Our Lies of P Trinity Sanctum Guide will go over how to find and unlock each of these mysterious rooms and get the End of Riddles achievement.
What are Lies of P Trinity Sanctums
Trinity Sanctums in Lies of P are a series of 5 rooms, often away from the main path you take through each level. Each one is locked, and can only be opened using a Trinity Key.
How to Get Trinity Keys
The majority of Trinity Keys are obtained by talking with the enigmatic Arlecchino, who will ring at a number of Phone Booths you come across. The earliest of these is in Area III, to the right before you cross the bridge to enter the factory.
Arlecchino will give you different riddles each time you pick up the phone while it's ringing. You'll get the Trinity Key regardless of how you answer, though answering correctly will give you Humanity (needed for one of the Special Weapons).
Lies of P Riddle Answers
- “Monster” or “Human” - Human
- “Boa Constrictor” or “Candle” - Candle
- “Egg” or “Glass” - Egg.
- “Bruis” or “Ergo” - Ergo
- “Yes” or “No” - Yes. This one gives a unique key needed to open the last Trinity Sanctum.
Note that the third riddle only gives you a hint to finding a key. The key itself is in Area VII, inside the Exhibition Hall. During regular exploration, you'll come across two statues next to a pedestal. Rotate the right statue twice to open the pedestal and claim the key.
