The final cipher ofLies of P: Overture, the Frosted Cipher, is the most difficult of the puzzles to solve. However, those who want to find all the clues about the truth behind the Alchemists and receive the special Sherlock Holmes outfit must take on and complete this final challenge.

Although you’ll get the cipher early, you’ll have to hold onto it for a while before you’ll be able to unlock the location the cipher leads to. In fact, opening the cipher at all will require you to get your hands dirty as, this time, Alidoro won’t be able to help you.

Player takes the Frosted Cipher Machine in Lies of P: Overture.

Where To Find The Frosted Cipher

The Frosted Cipher Machine is locatedat the end of the Frozen Coast area. It is right before the Ship Exterior Stargazer, but reaching it from that Stargazer is impossible as it is on the other side of the drop-off.

Guarded by a strong enemywho bursts out of the hull of a dilapidated ship, you’ll have tofight for your rightto access the cipher’s location.

Once the enemy is defeated, you cantake the Frosted Cipheras a rewardfrom the nearby vaultnext to the drop-off to the Ship Exterior Stargazer.

You cannot take this Frosted Cipher to Alidoro, the Tracker, at Eventide Hotel Krat just yet. He does not have the key to open it.
