Trinity Sanctum Lies of P Location and Walkthrough

The dark and atmospheric world of Krat in Lies of P is filled with challenging encounters, intricate lore, and deeply hidden secrets. Among the most rewarding objectives for completionists are the elusive Trinity Sanctums, which contain unique outfits, defensive gear, and valuable upgrading materials. Accessing these hidden vaults requires keen observation, a sharp mind for solving riddles, and a complete understanding of how to obtain the necessary keys.
How to Obtain Trinity Keys
Before you can step inside any of the hidden sanctums, you must first secure a Trinity Key by interacting with the ringing phone booths scattered across Krat. The mysterious King of Riddles will present you with a brainteaser that you must answer correctly to earn your prize. If you happen to fail a riddle, you can still acquire the key later by offering a specific item at the booth, ensuring you are never permanently locked out of the rewards.
Locating the Early Sanctums
The first Trinity Sanctum can be discovered relatively early in your journey within the gloomy depths of the Workshop Union Culvert. You will need to navigate past the rolling fireballs and explore the side corridors until you spot a distinctive door marked with a glowing triangle symbol. Unlocking this door rewards you with useful early-game defensive gear that can significantly boost your survivability against upcoming bosses.
As you progress into the subsequent chapters, the second sanctum awaits inside the stunning yet dangerous grand library of St. Frangelico Cathedral. Drop down into the lower sublevels near the wooden rafters to locate the hidden entrance embedded in the stone walls. Inside this vault, players will uncover rare quartz and excellent specialized armor items to enhance their character builds.
Discovering the Late Game Vaults
The third hidden vault requires careful navigation through the grand exhibition galleries, where players must solve a quick environmental statue puzzle adjacent to the ringing phone. Once the King of Riddles awards you the key, you can find the corresponding sanctum tucked away in the lower levels near the stage area. This room houses valuable mechanical parts that drastically improve your legion arm capabilities.
The fourth sanctum takes you back to Krat Central Station, situated behind a seemingly ordinary wall in the lobby area before heading out to the collapsed streets. Tracking down all these locations is highly recommended for anyone hoping to maximize their combat efficiency before facing the game's brutal final acts. For players who love showcasing their gaming accomplishments online, capturing your ultimate success across Krat and choosing to share your videos with the community is an excellent way to help others master these puzzles.
The Final Encounter and Rewards
The fifth and final Trinity Sanctum differs from the previous rooms because it requires the Chosen One's Trinity Key, which is acquired at the final phone booth location. Located deep within the Arche Abbey, this grand vault serves as the final resting place of the King of Riddles himself. Speaking with him uncovers major lore revelations and completes a lengthy side quest, rewarding you with the ultimate defensive accessory and a unique costume.
