Exploring Krat in Lies of P reveals numerous secrets, but few are as rewarding as the mysterious Trinity Doors scattered across the game's chapters. Unlocking these green-marked doors provides players with valuable defense gear, rare costumes, and essential lore regarding Arlecchino, the King of Riddles. Following daily gaming news and guides can help players optimize their exploration and collect every key without missing critical story beats.
How to Obtain Trinity Keys in Lies of P
Before opening any Trinity Door, players must obtain Trinity Keys by answering riddles posed by ringing public telephones throughout Krat. Answering these riddles correctly grants a key directly, while incorrect answers may require solving an extra task to claim your reward. Maintaining a careful tally of phone locations ensures you never leave a key behind during your playthrough.
Early Game Trinity Doors: Workshop Union and St. Frangelico
The first Trinity Door is located deep within the Workshop Union Culvert near the area where red pipes leak venomous liquid. Opening this door rewards players with the Blue Fox's Apparel alongside valuable quartz for upgrade progression. Moving forward to Chapter 4, another door sits at the bottom of the wooden scaffolding inside St. Frangelico Cathedral Chapel, offering protective amulets to bolster your defensive stats.
Mid-Game Trinity Doors: Estella Opera House and Krat Central Station
Inside the Estella Opera House, players can find a Trinity Door beneath the swinging burning chandelier before reaching the boss arena. Entering this hidden room yields high-tier defense parts that prove vital against mid-game enemies. Later in Chapter 9, a second visit to Krat Central Station leads to another door hidden near the lobby stairs, containing unique outfits and rare crafting materials.
The Final Trinity Sanctuary and Arlecchino's Meeting
The final and most significant Trinity Door is found in the Arche Abbey Outer Wall area near the bottom of the vertical lift shaft. Opening this sanctuary requires the Chosen One's Trinity Key, obtained by answering Arlecchino's final riddle in the upper towers. Stepping inside allows players to speak directly with the King of Riddles, completing his questline and securing the ultimate rewards of his collection.
