Navigating the dark and atmospheric world of Krat requires more than just mastering tense combat mechanics and parry timings. Players seeking to uncover the deep secrets hidden within the game will eventually encounter locked doors marked with a mysterious green triangle symbol. To unlock these specialized vaults, known as Trinity Sanctums, you must solve riddles presented by a mysterious figure over ringing telephones.

Answering the Call of the King of Riddles

The primary method for securing these prized items involves locating ringing telephone booths scattered across various chapters. When a phone rings, interacting with it connects you to Arlecchino, the self-proclaimed King of Riddles, who tests your intellect. Answering his query correctly immediately grants you a key, whereas a wrong answer requires finding a specific alternative path to obtain it.

The very first ringing phone is encountered in Chapter Three as you explore the Krat City Hall area just before the courtyard. Arlecchino will present a riddle about a monster, and choosing the correct answer yields your first key. Finding the right booth requires close attention to the distinct auditory ringing sound echoing through the rainy streets.

Tracking Down Later Phone Booths

As you progress deeper into the campaign, the locations of the telephones become significantly more hidden and dangerous to reach. The second phone is situated in the Malum District, tucked away within a courtyard crawling with decay and formidable enemies. Solving this riddle requires a keen understanding of human nature to satisfy Arlecchino's twisted curiosity.

For the third challenge, players must navigate the Grand Exhibition Gallery in Chapter Seven to locate the next ringing receiver. This specific event introduces an extra puzzle step involving two statues that must be rotated to face each other before the item drops. Successfully interacting with the environment ensures you do not miss this crucial step in the quest line.

Locating the Final Sanctums

The fourth telephone booth is located near the street level of the Krat Central Station Lobby during Chapter Nine. This encounter provides a more complex narrative choice, but maintaining a consistent approach will secure the next key without issue. The final interaction occurs in the Arche Abbey, completing Arlecchino's complex game and opening the path to his personal chambers.

Unlocking each matching door yields incredibly high-tier defensive gear, rare upgrading materials, and deep lore insights regarding the great inventor Venigni. Players who meticulously track every ringing telephone will gain a massive structural advantage for the challenging endgame boss encounters.
