Navigating the dark streets of Krat in Lies of P presents players with numerous formidable challenges, but few are as intriguing as the phone calls from Arlecchino. Known as the King of Riddles, this mysterious figure tests your intellect through ringing payphones scattered across various chapters. Solving these brainteasers grants valuable Trinity Keys that unlock hidden rooms containing crucial loot and character upgrades.

Finding Phone Booth Locations and Solutions

The first phone call occurs near Krat City Hall Courtyard, where the King of Riddles asks a classic riddle regarding human stages of life, to which the answer is Human. As you progress to Chapter V in the Malum District, another ringing phone will present a puzzle about a growing object, which is answered correctly with Candle. Later in the Grand Exhibition Gallery, answering Egg unlocks a unique environmental puzzle involving nearby statues that must be aligned to claim your reward.

Late Game Riddles and Moral Choices

In Chapter IX at Krat Central Station Street, players encounter a riddle regarding a blue flower, where the correct response is Ergo. Upon reaching the Relic of Trismegistus in Chapter X, Arlecchino poses a final moral inquiry asking if Geppetto's creation is a killer. Surprisingly, answering either Yes or No grants access to the final Trinity Key needed for completion.

Unlocking Trinity Sanctums for Rare Rewards

Each Trinity Key obtained allows players to open designated Trinity Sanctums hidden throughout Krat's complex levels. These secret chambers contain valuable materials such as Quartz, unique defensive wear, and rare outfits. Finding all phone locations and opening every door is essential for completing full play-through achievements.
