In total, there are five Trinity Sanctum Doors scattered around Krat for you to find. They can be a bit tricky to find but we will tell you how to find all of them, so make sure to keep reading if you need to find the Trinity Doors in Lies of P.

The first Trinity Door isn’t found until Act Three when you make your way to the Workshop Union Culvert.

  • From the Workshop Union Culvert Stargazer, go up the steps that lead into the sewer, but be careful of the fireball that will easily take out half of your health
  • Make your way carefully up the hill and then turn right at the passage that is closest to the end of the tunnel
  • Once you’ve done that, follow the path out, turn left, and go into the next indoor area of this section
  • Turn right instead of going through the red tunnel. Follow the passage until you see a Trinity Door on the left. Use the key and you will go inside to be given a Quartz and the Blue Blood’s Tailcoat

These riddles are given to you over the phone by Arlecchino. Make sure you have the sound effects turned up, as Arlecchino will be contacting you over a ringing payphone. Corresponding with each door, there are five riddles that you will have to answer from him. However, don’t panic if you don’t know how to find the payphones, as we will have a step-by-step on how to find each payphone along with the answer. 

Riddle one: Krat City Hall

  • Work through the streets from the Krat City Hall Stargazer.
  • There will be a bridge that leads to the Workshop Union. Instead of crossing it, head through the passage on the right that will take you to the phone. Arlecchino will ask you the answer to the riddle, which is Human

Riddle two: Malum District

  • Climb the ladder, and you’ll see the second phone. The answer to the riddle is Candle

Riddle three: Grand Exhibition Gallery

  • From the Grand Exhibition Gallery Stargazer, fight a room full of puppets that are trying to break through the gate. Then, you will find the phone in a room just past this, where the answer to the riddle is Egg
  • However, you won’t get the key until you find the “Woman of Cold”
  •  From the phone, walk the linear path until you reach a machine gun-wielding enemy. Get rid of them, and then there will be a room with two statues
  • The one on the right can be turned twice so that it matches the one on the left. Once you have completed this, it will reveal a slot where you can grab the Trinity Key from it

Riddle four: Krat Central Station Street Stargazer

  • Go through the alcove and follow the straight path ahead
  • When you reach the crossroads, look to the left and you will see the payphone. The answer to this riddle is Ergo

Riddle five: Relic of Trismegistus Stargazer

  • Above the entrance to the boss door, there is a cliff
  • On top of this cliff, you will find the payphone. It’s pretty hard to miss. You can answer either Yes or No to this riddle
