The dark and atmospheric world of Krat holds many dangerous secrets, but few are as compelling as the ringing telephones scattered throughout its gloomy streets. These ringing payphones connect the player directly to Arlecchino, the self-proclaimed King of Riddles, who tests your wit with various mental puzzles. Successfully answering his questions rewards you with unique keys that unlock valuable treasures hidden away behind intricate doors.

Understanding the Payphone System and Trinity Keys

As you progress through the main story, certain telephones will begin to ring dynamically when you approach their designated locations. Interacting with these phones initiates a conversation with a mysterious voice that demands a correct answer to an esoteric riddle. Solving these puzzles correctly grants players a specialized item known as a Trinity Key, which fits into hidden green doors found later in the zones.

Missing a phone call or answering incorrectly does not permanently lock you out of the rewards, but it can delay your progress significantly. Managing your choices carefully within your active Steam account tracking system ensures you do not miss these highly valuable exploration checkpoints. Each unlocked chamber contains powerful defensive gear, unique outfits, and rare upgrade materials that are crucial for survival.

Solutions to Every Arlecchino Puzzle Encountered

The first riddle you encounter asks about a morning creature that walks on four legs, afternoon on two, and evening on three. The correct answer to this classic riddle is human, which immediately secures your very first key. The second puzzle focuses on a concept that is made of stone but grows softer when exposed to the elements, leading to the solution of an egg.

Later in the journey, Arlecchino will present more complex queries that require a deeper understanding of human nature and logic. The third puzzle revolves around a concept regarding what cannot be bought but can be broken by a single look, which is a candle or a secret depending on the phrasing. Finally, the last major riddle deals with the duality of truth and deception, forcing players to think critically about the puppet rulebook before answering.

Locating and Unlocking the Hidden Trinity Sanctums

Once you have gathered the keys from the ringing payphones, you must seek out the hidden sanctuary doors spread across Krat. The earliest sanctuary is located deep within the Workshop Union Culvert area, tucked safely away from the rolling boulder traps. Another prominent green door can be found near the Opera House stage, requiring careful navigation past powerful automated puppets.

The final and most important sanctuary is located near the endgame areas within the Arche Abbey structure. Unlocking this final room allows players to meet the King of Riddles face to face for a revealing conversation. Speaking with him provides deep lore context regarding the grand puppet experiment and offers a final choice that impacts your collection.
