All Lies of P Trinity Door locations

Throughout your journey in Lies of P, you’ll find ringing phones scattered across Krat. Every time you answer a 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 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

To find the Trinity Keys in Lies of P, you need to be on alert for the five Ringing Phones in areas III, V, VII, IX, and X, and then answer each of Alrecchino’s riddles. If you’re having trouble finding the phones or answering a particular riddle, you can use our guide detailing all Arlecchino phone riddle answer and locations.

Once you’ve got the answers and have your Trinity Keys, you’ll find that the doors they go to are a bit harder to find.

Where to use Trinity Keys in Lies of P

To use the Trinity Keys in Lies of P, you need to find all five of the Trinity Doors in their respective areas, which are:

• Area III: Workshop Union Culvert
• Area IV: St. Frangelico’s Cathedral Chapel
• Area VI: Estella Opera House
• Area IX: Krat Central Station Lobby
• Area XI: Arche Abbey Outer Wall

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. Let’s dive straight into where you can find all the doors.

1) Area III: Workshop Union Culvert

The first Trinity Room you’ll encounter is in Area III.

1. 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.
2. Proceed uphill through the tunnel, carefully avoiding the rolling balls.
3. Turn right down the passage closest to the end of the tunnel.
4. 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.
5. Instead of going left through the red tunnel, go right and follow the passage until you see the first Trinity Room on the left.

In the safe found in the first Trinity Room, you’ll find the following rewards:

• Quartz
• Blue Blood’s Tailcoat

2) Area IV: St. Frangelico’s Cathedral Chapel

1. From the St. Frangelico’s Cathedral Chapel stargazer in Area IV, head into the cathedral.
2. 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.
3. 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.
4. Carefully avoid the electric ball and head up the slope.
5. 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.
6. Proceed up this ramp, carefully avoiding the ball, and there’s a Trinity Room on the left-hand side of the tunnel.

Once you’re inside the second Trinity Room, you’ll find the following rewards:

• Black Cat Amulet
• Monster Sweeping Hunter’s Apparel

3) 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.

1. 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.
2. 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.

Now that you’re in one of the easier-to-find Trinity Rooms, open the safe and grab these rewards:

• Quartz
• Belford Superior Radiation Converter

4) Area IX: Krat Central Station Lobby

This Trinity Door is 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.

Search the room and loot these rewards:

• Carrier’s Amulet +1 (One of the 10 best amulets in Lies of P)
• Workshop Master’s Workwear

5) Area XI: Arche Abbey Outer Wall

1. In Area XI, proceed until you reach the Arche Abbey Outer Wall stargazer.
2. Continue through the level until you reach a tall indoor area with wooden beams that span the length of the room.
3. Descend using the wooden beams and ladders.
4. Find the final Trinity Room at the bottom of the area.

This door is a little different than the others, as it requires a specific key to enter. If you’ve solved all the previous riddles and then taken care of the final one, you should have the Chosen One’s Trinity Key, the only one that can open the room.

Inside the final Trinity Room, you’ll find the King of Riddles himself, and he’ll ask you one final question:

• “Are you a puppet or a human being? Which one are you?”.

Your answer will get different reactions from Arlecchino, but the good news is that it won’t change the rewards you’ll receive.

The rewards in the final Trinity Room are:

• Quartz
• Alchemist’s Cape

Should I kill Arlecchino in Lies of P?

The matter of whether to kill or not to kill Arlecchino in Lies of P is the last decision you’ll have to face at the end of your quest to find all the Trinity Rooms. When you hear the story of all the horrible deeds that Arlecchino has committed and also find out that he doesn’t feel any shame about them, it will be up to you to decide his fate.

While he may now be a harmless puppet, perhaps the morally right choice would be to end him right there. When you attack him, he won’t be able to move. While this might make you feel a bit bad, maybe you’ll be satisfied to know that once he’s dead, he’ll drop a Radiant Ergo.
