Throughout your journey in Lies of P, you’ll find ringing phones scattered across Krat. Every time you pick up the phone, Arlecchino, the “King of Riddles,” will give you a riddle to solve. Answer his riddle and you’ll get a Trinity Key, which opens one of the five locked Trinity Rooms hidden around Krat.
Inside Trinity Rooms are valuable treasures, like cosmetic items, puppet parts, and Quartz for you to upgrade your P-Organ, so you should always be on the lookout. Whenever you get a Trinity Key, make sure to backtrack to a locked Trinity Door and open it to claim its loot.
Krat isn’t the most intuitive place to navigate, but this guide is here to help. We’ll give you exact directions to every Trinity Room in Lies of P and tell you what rewards are inside.
How to find Trinity Keys in Lies of P
There are five Ringing Phones (and Trinity Keys) in Lies of P, and luckily they aren’t too difficult to find. Simply stay on alert for any ringing phones in areas III, V, VII, IX, and X, and you should have your Trinity Keys in no time. If you’re having trouble finding the Ringing Phones or answering a particular riddle, you can use our guide detailing all Arlecchino phone riddle answer and locations.
Once you have your Trinity Keys, you’ll find that the doors they go to are a bit more hidden.
Where to use Trinity Keys in Lies of P
Of the five Trinity Doors in Lies of P, four need Trinity Keys and one requires the Chosen One’s Trinity Key that you get by answering Arlecchino’s final phone riddle. These doors are a bit more hidden than the keys themselves, but it shouldn’t take too much doing to find them.
Area III: Workshop Union Culvert
The first Trinity Room you’ll encounter is in Area III.
- From the Workshop Union Culvert stargazer, head up the steps leading to the sewer area and into the tunnel with the rolling ball of fire hazards.
- Proceed uphill through the tunnel, carefully avoiding the rolling balls.
- Then turn right down the passage closest to the end of the tunnel.
- Follow the path out and turn left, going past the area where you met Red Fox and Black Cat, and proceed onward into the next indoor area.
- Here, instead of going left through the red tunnel, go right and follow the passage until you see a Trinity Room on the left.
Rewards:
- Quartz
- Blue Blood’s Tailcoat
Items like the Blue Blood’s Tailcoat are Outfits. Any Outfit you find won’t alter your gameplay or grant any type of buffs, but they do allow you to customize Pinocchio so that you can take back Krat in style.
Area IV: St. Frangelico’s Cathedral Chapel
- From the St. Frangelico’s Cathedral Chapel stargazer in Area IV, head into the cathedral.
- Walk down the broken path leading into the hole in the ground, and climb down the ladder.
- You’ll enter a room with lots of wooden scaffolding, clockwork mechanisms, and ladders leading upward.
- Head up the ladders, cross the rafters, then go down the ladder on the other side of the rafters and you’ll reach an area with an electric ball hazard.
- This is the level’s mandatory route, so you can’t miss the path.
- Carefully avoid the electric ball and head up the slope.
- At the top of the slope, there’s a small alcove on the right with a ladder leading to another ramp above. Climb the ladder to get to a secret area.
- You’ll find yourself on the top level where the electric balls are dropping down from.
- Proceed up this ramp, carefully avoiding the ball, and there’s a Trinity Room on the left-hand side of the tunnel.
If you’re in a hurry and find all of this wandering exploration to be taking too long, you can use your Sprint button to ascend or descend ladders more quickly. (B on Xbox, Circle on PlayStation, or Spacebar on PC)
Rewards:
- Black Cat Amulet
- Monster Sweeping Hunter’s Apparel
Area VI: Estella Opera House
The Trinity Door in Area VI is in Estella Opera House. It’s at the bottom of the room just before the stage where you encounter the boss, with the narrow beam and swinging chandelier.
- Proceed through the level via the mandatory route until you get to this room.
- It’s hard to go wrong, as the level is fairly linear, although the enemies themselves can be quite tough.
- Instead of crossing the narrow beam toward the boss arena, drop down and turn around — there’ll be a Trinity Room right in front of you.
Rewards:
- Quartz
- Belford Superior Radiation Converter
Not sure what to do with all of the Quartz you’re collecting? You’ll want to regularly visit Geppetto’s office on the second floor of Hotel Krat and interact with the P-Organ. This lets you assign all of your gathered Quartz into different buffs and skills.
Area IX: Krat Central Station Lobby
This one’s hard to miss. In Area IX, from the Krat Central Station stargazer, go down the stairs on the left of the station exit. This door was closed on your first visit here, but now it’s open, and the Trinity Room is directly ahead.
Rewards:
- Carrier’s Amulet +1
- Workshop Master’s Workwear
Area XI: Arche Abbey Outer Wall
- In Area XI, proceed until you reach the Arche Abbey Outer Wall stargazer.
- Continue through the level and you’ll eventually enter a tall indoor area with wooden beams that span the length of the room.
- At the bottom of this indoor area is the final locked Trinity Room.
This door is a little different than the others, as it requires a specific key to enter: The Chosen One’s Trinity Key. You get this by answering Arlecchino’s final phone riddle. You’ll find the King of Riddles himself inside, and he’ll ask you a final question.
Rewards:
- Quartz
- Alchemist’s Cape
