In Lies of P, answering the cryptic phone calls from Arlecchino, the King of Riddles, is essential for unlocking valuable Trinity Sanctums throughout Krat. Players who answer these questions correctly receive Trinity Keys, which grant access to hidden rooms filled with rare gear, Quartz, and unique outfits. Understanding how to solve every puzzle ensures you never miss out on key progression rewards during your journey.

Finding the Ringing Telephones in Krat

Ringing payphones are scattered across various chapters of the game, often positioned near main progression paths. Interacting with a ringing receiver initiates a conversation with Arlecchino, who presents a unique brain teaser. Navigating to these specific telephone locations during your exploration triggers the necessary events to secure keys.

Early and Mid-Game Riddle Solutions

The first riddle encountered near the Venigni Works asks about a creature that walks on four, two, and three legs, for which the correct response is Human. In the Malum District, Arlecchino asks about something tall when young and short when old, which refers to a Candle. When visiting the Grand Exhibition, the riddle regarding what cannot be used before it breaks requires selecting Egg.

Late-Game Challenges and Final Questions

Upon reaching Krat Central Station Street, players are asked about a blue flower taking root on a man, where the correct choice is Ergo. Later in the campaign, Arlecchino poses a moral question asking whether Geppetto's creation is a killer. Answering either Yes or No rewards players with the final key or a surprise box containing it, allowing full access to all secrets.

Unlocking Trinity Sanctums for Rewards

Once a key is acquired, players can seek out matching green doors hidden in areas like the Estella Opera House and St. Frangelico Cathedral. Exploring these vaults allows you to discover powerful equipment upgrades, including a Haligtree Secret Medallion (Left) along with rare materials. Completing Arlecchino's entire storyline ultimately provides deep lore insights and unlocks the End of Riddles achievement.
