Navigating the dark and treacherous streets of Krat requires more than just mastering brutal soulslike combat mechanics. Scattered throughout the decaying world of Lies of P are mysterious, green-glowing portals known as Trinity Sanctums that hold powerful defensive gear and unique outfits. Unlocking these secret chambers requires players to interact with ringing telephones and solve cryptic riddles posed by the enigmatic King of Riddles, Arlecchino.
How to Acquire Trinity Keys via Phone Riddles
Before you can open any of the hidden rooms, you must first secure a corresponding key by answering a riddle correctly. Ringing telephone booths can be found across various chapters, including the dark alleyways of Elysion Boulevard and the grand corridors of the Malum District. If you accidentally provide the incorrect answer to a prompt, you can still obtain the key by offering a rare asset like Bright Red Apples to complete the interaction.
Understanding the exact puzzles allows you to bypass potential resource costs and efficiently build your inventory. For instance, the initial riddle asks about a human creation that cannot be touched but can be broken, which refers directly to a promise. Solving these interactions successfully grants you the green token required to access the hidden treasure vaults scattered across the map.
Tracking Down the First Three Sanctum Locations
The earliest sanctuary is located deep within the Workshop Union Culvert, tucked away near the massive rolling fireball trap. Players must navigate past the fiery hazards and locate a secluded tunnel pathway that leads directly to the marked door. Inside, explorers will discover the Blue Blood Tailcoat costume alongside a helpful quartz upgrade piece.
The second door awaits inside the St. Frangelico Cathedral Chapel, requiring careful exploration of the lower flooded structural levels. You will need to climb up the wooden scaffolding and drop down into a hidden alcove to find the glowing doorway. Opening this chamber provides the Vanguard Readiness defensive liner, which significantly boosts your elemental damage resistance attributes.
Moving forward into the campaign, the third room can be discovered within the Estella Opera House stage area. Just before entering the main boss arena, look beneath the swinging blazing chandelier to find a small wooden drop point. Descending into this lower hallway reveals the hidden entrance housing the highly sought-after Workshop Master Apron outfit.
Finding the Final Doors and the King of Riddles
The fourth sanctuary is positioned inside the Grand Exhibition Gallery, shortly after solving a separate statue orientation puzzle. Following the gallery corridors leads to a dead-end room where the green door stands out against the stone walls. Unlocking this vault grants you the Carrier Amulet plus one, which greatly expands your total weight capacity limit.
The final room resides in the deeply subterranean Arche Abbey Outer Wall area near the end of the narrative journey. Reaching this final chamber requires clearing out powerful elite enemies guarding the vertical stone platforms. Inside this ultimate vault, you will finally meet Arlecchino face-to-face to uncover the deep lore surrounding the puppet frenzy.
