If you’ve been wandering the grim streets of Krat, chances are you’ve already heard one of those eerie ringing phones echoing through the city. Each call isn’t just a spooky moment — it’s a test. On the other end is a voice full of riddles, and answering correctly earns you a Trinity Key, the only item that unlocks the shimmering Trinity Doors scattered across Lies of P. These hidden rooms contain some of the best gear and materials in the game, so every riddle is worth solving.
Below you’ll find the complete list of all five phone riddles, their exact locations, and the correct answers so you can grab every Trinity Key without wasting time backtracking.
Phone 1 – Krat City Hall Courtyard (Chapter II)
Your first encounter with the ringing phone happens soon after the Krat City Hall Courtyard Stargazer. Push forward into the narrow streets until you reach a bridge that leads toward the Workshop Union. Before crossing, turn right into a side passage — the phone is waiting there. If you’ve already progressed further, you can backtrack from the Workshop Union Entrance Stargazer to find it.
Answer: Human
Solving this first riddle introduces you to the mysterious “King of Riddles” and rewards you with your initial Trinity Key, setting the tone for the puzzles ahead.
Phone 2 – Malum District (Chapter V)
The next phone can be tricky to spot amid the chaos of the Malum District. Head to the area with the large bonfire in the center courtyard — that’s your landmark. From the Malum District Stargazer, step into the Red Lobster Inn, turn left into the main room, and exit via the staircase at the back. Follow the winding streets until you reach a ladder on the right just before the courtyard. Climb up, and you’ll hear the phone ringing above.
Answer: Candle
Answer correctly, and you’ll earn your second Trinity Key, inching closer to the full set.
Phone 3 – Grand Exhibition Gallery (Chapter VII)
You’ll naturally come across the third phone as you fight through the Grand Exhibition Gallery. After defeating the blade-wielding automaton that crashes through a gate, listen for the phone echoing from a nearby hallway.
This riddle’s answer alone won’t grant the key — you’ll need to solve a small environmental puzzle involving the Woman of Cold statue afterward. Complete that side task to claim the next Trinity Key.
Answer: Egg
Phone 4 – Krat Central Station Street (Chapter IX)
Starting from the Krat Central Station Street Stargazer, move straight ahead through the alcove and follow the linear route. When the path splits left and right, take the left turn to find the next phone waiting at the dead end.
Answer: Ergo
This riddle marks the point where the King of Riddles’ motives start to feel personal, adding another layer to Lies of P’s dark mystery.
Phone 5 – Relic of Trismegistus Entrance (Chapter X)
The final phone appears near the endgame. From the Relic of Trismegistus Entrance Stargazer, head toward the cliff overlooking the boss door. You’ll spot the phone right above, impossible to miss as the atmosphere grows tense.
Answer: Yes
Solving the last riddle completes your collection of Trinity Keys, giving you access to all the locked Trinity Doors scattered throughout Krat. Inside, you’ll find powerful gear, rare upgrade materials, and sometimes lore snippets that shed light on the King of Riddles himself.
Why Trinity Doors Matter
Beyond their valuable loot, Trinity Doors often contain hidden outfits and cryptic notes that expand the game’s worldbuilding. Opening all of them rewards meticulous explorers with both gameplay advantages and deeper understanding of Lies of P’s lore. If you’re aiming for 100 % completion — or just want to look stylish while dismantling puppets — these rooms are essential.
Final Tips for Puzzle Hunters
Each phone call can only be answered once, so double-check before responding. If you miss one, you can revisit earlier chapters using unlocked Stargazers. Also, keep your audio up — that faint ringing sound is your best clue when exploring new areas.
The riddles in Lies of P blend atmosphere with storytelling, turning what could’ve been throwaway puzzles into moments of haunting personality. Whether you’re here for completion or curiosity, every ring on the line brings you closer to unraveling Krat’s strangest mystery.
