Exploring the dark and twisted streets of Krat in Lies of P often rewards players who pay close attention to environmental secrets. Among the most lucrative mysteries are the hidden Trinity Rooms, locked behind distinct green doors marked with a triangular emblem. Unlocking these chambers requires finding specific keys by answering riddle prompts given by the elusive King of Riddles via ringing telephones scattered throughout the game.
How to Acquire Trinity Keys
To begin opening these secret rooms, you must locate the ringing payphones found across various chapters. Interacting with these phones initiates a conversation with Arlecchino, the King of Riddles, who presents a unique brain teaser. Answering the riddle correctly will immediately grant you a Trinity Key, while a wrong answer might require a different method or resource to obtain the key later.
There are five unique keys available throughout the narrative journey, including the final Chosen One's Trinity Key. Each key corresponds to a specific chamber, and players should make it a habit to answer the phones as soon as they start ringing during exploration. Successfully solving these riddles is the primary method to unlock the rare loot waiting inside the hidden sanctuaries.
Every Trinity Door Sanctuary Location
The first Trinity Door is encountered relatively early inside the Krat City Hall area, located just before the fight with the Scrapped Watchman. Descend into the lower corridors near the workshop area to find the glowing green door waiting to be opened. Inside, players can discover the Blue Blood's Tailcoat alongside important defensive upgrades.
As you progress further into the industrial zone, the second door can be found within the claustrophobic layout of the Malum District. Look for a large room filled with decayed enemies shortly before encountering the Black Rabbit Brotherhood. Unlocking this sanctum provides the Monster Sweeper's Hunting Apparel, giving players an aesthetic boost along with practical defense.
The remaining sanctuaries are located within advanced areas like the Grand Exhibition Gallery and the Krat Central Station Lobby. The final hidden chamber requires the Chosen One's Trinity Key and is found deep within the Arche Abbey toward the climax of the game. Visiting these late-game locations allows you to conclude the riddle storyline and meet the mysterious entity behind the phones.
Valuable Sanctum Rewards and Upgrades
Opening every single room serves as an excellent way to prepare your puppet character for the grueling challenges ahead. The chests hidden inside contain premium defense parts, quartz for upgrading your P-Organ system, and unique cosmetic outfits. These items significantly enhance your survivability against aggressive bosses and elite monsters roaming the late-game zones.
Additionally, fully exploring these rooms provides a deeper understanding of Krat's tragic history and the background of the puppet rebellion. Meeting the King of Riddles in the final chamber unlocks deep lore conversations and unique quest conclusions. Prioritizing these side puzzles ensures you do not miss out on powerful equipment necessary for optimizing your build.
