In Chapter 4, enter the Salt Storage room in the Arkham Fish Market’s Cutting Area by selecting I, IV, IX, and XVI on its Roman-numeral lock, then destroy the green, crystallized body inside. Opening the door alone does not unlock The Damned.

Where to find the Salt Storage lock

In Chapter 4, reach the Arkham Fish Market and head to the Cutting Area. The trophy-related lock is on the Salt Storage door. It is a wooden panel that takes Roman numerals, not a decimal keypad.

To solve it from clues, find The 16 Punishments of the Sailor, described as a board in the pub. Then read Instructions to Sybil near the stairs leading toward Ma Fishface. The clue name may appear as “Sibil” in some guides; use the spelling shown in your game if you refer to it.

How the clue gives you the combination

The instructions identify four punishments: being confined to the ship, deprived of beer, tarred and feathered, and keelhauled. Match those punishments to entries 1, 4, 9, and 16 on the sailor-punishment list. Enter their Roman-numeral equivalents:

  • I for 1
  • IV for 4
  • IX for 9
  • XVI for 16

Select all four symbols on the Salt Storage lock and validate the selection. The order does not matter.

Optional square-number clue

Warning for Sybil, found in the Jewelry Workshop, points to square numbers: 1, 4, 9, and 16. This can confirm the pattern, but it is not necessary if you have matched the punishments to the numbered list.

What to do after opening the door

Go into Salt Storage and destroy the green, crystallized body. Guides describe actions such as stomping, kicking, using a melee attack, or shooting it; the essential step is to break the body. That completes the investigation and triggers The Damned trophy, whose achievement wording is “Investigate the sixteen punishments.”

Common mistakes

  • Stopping at the open door: The trophy trigger is destroying the body inside.
  • Entering decimal digits: Use the Roman numerals I, IV, IX, and XVI on the panel.
  • Using the nearby safe code: The Locker Room safe’s code is 1496, but it is separate from the Salt Storage lock.
