A safe first-room check

The achievement text confirms the first build, not a required room, cost, or construction order. Before confirming a room, look at the current screen and choose based on the problem you're facing this cycle:

  1. If a Knight needs task support or damaged armour is the immediate problem, inspect the Forge option.
  2. If a difficult assignment needs temporary stat help, inspect Alchemy.
  3. If missing Knight information is causing mistakes, look for the information-focused option available to you.
  4. If none of those solves a current problem, keep resources until the next request makes the trade-off clearer.

Before you confirm the build

Compare the room's displayed cost with your Treasury and the next issue you can already see. For instance, choose between investigating a Knight and repairing equipment according to the information or equipment problem in your run; the achievement description does not require either room. If the build option is unavailable, check the current Gallery screen and your available resources first. The sources do not establish every prerequisite, so an unavailable option alone does not identify the missing condition.

After the room is built, check the Steam achievement list. The public description does not explain the exact registration timing or offline behavior; keep the game version and the room name if you need to report a problem.

What not to assume

Steam does not say which room must be built, when it becomes available, whether rooms have a universal best order, or that a room build guarantees a quest result. Read the cost and effect in your current build before spending.

The annexes guide explains the confirmed roles of the Gallery, Forge, Alchemy, and other Tower support rooms. For resource planning before a build, use the spoiler-light tips.
