How to Unlock the Armory in Blue Prince

Unlock the Armory by completing the Precipice chess puzzle and choosing Mantle of the Knight. Then keep drafting: the room is added to the pool, not guaranteed in each run.

To unlock the Armory room in Blue Prince, solve the chess puzzle in the Precipice and select Mantle of the Knight. That adds the Armory to the room-drafting pool; it does not guarantee that the room will appear in your next draft.

How to unlock the Armory

  1. Reach the Precipice and solve its chessboard puzzle by placing all six chess pieces on the tiles that match the rooms where you found them. A correctly placed piece lights up. Once all six are in place, the panels behind the board open. The Precipice puzzle guide describes the board and its solution.
  2. Choose Mantle of the Knight from the chess powers. This is the choice that adds the Armory to the rooms you can draft. The Armory room page lists it as a Knight-associated room.

The board is a non-standard 9-by-5 chessboard, and each chess-piece type appears once. Match pieces to the locations where you found them; you do not need to draft the Armory to solve the puzzle or unlock this power.

Why the Armory may not appear right away

Unlocking a room makes it eligible to enter the draft pool, but does not force it into a particular run. Keep drafting if it does not appear. The Armory is a Shop and Blackprint room, and a Shops-restricted draft can make it more likely to encounter—but does not guarantee—the Armory. The Shop room guide describes ways to initiate a Shops-restricted draft: use the gold book in the Secret Passage or use the Prism Key on a locked Shop door. These methods raise the chance of seeing a Shop, not this specific Shop.

Armory drafting restrictions

The Armory cannot be drafted into every grid position. Its room page lists position restrictions; if your current game behaves differently from an older guide, rely on the in-game rules, which may change with patches. See the Armory page for the listed restrictions.
