The Stolen Sign: reveal the clue route

Reveal solution / story details

Reported remake route from Skeith Ruch and Julio La Pine, published September 17. Neither specifies a platform or build; Kingy has not play-tested these steps.

On the hand-in, Raider King says the quest clears with Fey, and Rival Mech Boss's no-commentary recording (September 28) shows the same: after the Fey scene the game cuts to the party with Kilika outside the Guild and displays "Quest Stolen Sign completed!" without a walk back. The Nerd Stash sends you back to the Guild instead, so if your log still lists the quest as pending, report there.

  1. Accept The Stolen Sign at the Zeiss Bracer Guild.
  2. Inspect the back of the town clock for the next clue.

Probe for Parts: reveal the request walkthrough

Reveal solution / story details

Neoseeker reports this remake procedure; platform/build unspecified, not yet tested by Kingy.

The guide says a room’s orange minimap circle disappears when its parts are collected. Exact reward, expiry and platform parity have not yet been tested.

  1. When the request appears at Zeiss’s Guild, speak to Erik on the Central Factory’s ground floor for the Special Alloy Detector.
  2. Search the 3F Workshop (three parts) and 4F Laboratory (four). Activate the detector, then examine the revealed sparkle to collect.

    On the 3F Workshop floor, use the Special Alloy Detector near the machines. Where the “Examine” prompt and magnifier appear, examine the spot, then sweep the next machine.

  4. Check for eight parts before reporting to Erik; preserve a separate save until you inspect the result.

What this chapter reference establishes

Classic SC places Chapter 2 in Zeiss for the earthquake investigation. Rolent belongs to Chapter 4.

The cited source covers the original SC. It does not establish remake item locations, BP answers, encounter values or missable deadlines.

Make the Chapter 1 handoff deliberate

Kingy recommends checking the imported file’s party, inventory and quest state before overwriting the original demo save.

The official site establishes the story frame and platforms, but it does not publish a remake-only chapter checklist. Use the in-game journal as the primary authority for names and triggers.

  1. Load the full-game file and create a new manual save before taking the next airship or regional assignment.
  2. Check the party menu, Quartz, money, key items, Recipe Book and Fishing Notebook.
  3. Read the Guild board and quest log before following the main marker.
  4. Record any unfamiliar chapter label or objective wording; it is better evidence than a copied classic guide.

Use the regional loop as your route skeleton

Classic SC places this investigation in Zeiss. Use this comparison to identify the chapter an older guide covers; its item and quest instructions still need remake verification.

Route anchorWhat to check
Current regional arrivalCheck the location shown by your current map before using an older walkthrough.
Bracer Guild boardAccept or record optional work before major story transitions; exact BP values still need remake gameplay verification.
Town and field mapsSpeak to changed NPCs after story beats and watch for journal updates rather than assuming classic timing.
Chapter departureReview collection notes and keep a return save before the next regional lock-in.

Build a reliable optional-content pass

These two quest procedures have remake sources. Other Chapter 2 quests, deadlines, BP totals, books, recipes, fish, chests and party availability still need current evidence. The older demo-only walkthrough does not establish this full-game route.

Keep a separate save before a chapter transition if optional content matters to your run.

  1. Finish only the requests whose current objectives and rewards you can see in the release build.
  2. Update the Recipe and Fishing Notebooks after each town or field visit.
  3. Capture a screenshot or note for any missable warning, unusual reward or chapter transition.
  4. Keep the pre-departure file until the next region has loaded and the checklist is complete.

Spoiler gate: the larger conspiracy

Reveal solution / story details

[Spoilers] The official story presents the journey as a search that expands into a conspiracy affecting Liberl. Keep this section closed if you are using the page as a first-playthrough planner.

Named allies and adversaries are catalogued separately so a character reference does not accidentally become a plot reveal.
