Trails in the Sky 2nd Chapter lighthouse puzzle overview

The Trails in the Sky 2nd Chapter lighthouse puzzle appears during Chapter 1, “Sneaking Shadows,” as part of the hidden Lighthouse Test Run quest. The objective is not marked like a standard Bracer assignment, so the conversation with Vogt is easy to overlook.

The quest takes place at Varenne Lighthouse, where Vogt needs help testing the lighthouse’s newly replaced components. The task begins through dialogue rather than a conventional quest board. If the wrong response is selected, the test run will not become available during that visit.

Missable Quest Warning

Do not end the conversation with Vogt by only telling him to take care of himself. Select the option asking whether there is something you can do for him.

Quest DetailInformation
Quest nameLighthouse Test Run
Japanese title灯台の試運転
ChapterChapter 1: “Sneaking Shadows”
LocationVarenne Lighthouse
Key NPCVogt, the lighthouse keeper
Quest typeHidden quest
Main objectivePerform a lighthouse test run
Bonus objectiveAsk whether anything else can be done

The quest becomes available after the investigation advances far enough for the relevant testimony to be heard. Because it is hidden and time-sensitive, it should be handled before traveling to Zeiss at the beginning of Chapter 2.

Find Vogt

Go to the top floor of Varenne Lighthouse and speak with the lighthouse keeper.

Read the Manual

Inspect the bookcase near the control area before operating the lighthouse panels.

Earn Bonus BP

After the test finishes, ask if there is anything else you can do for Vogt.

Best Timing

Complete this quest soon after it becomes available in Chapter 1. Waiting until the next chapter can cause the opportunity to expire.

How to unlock the lighthouse test run

The central challenge is starting the quest correctly. Vogt speaks indirectly about his back pain and the unfinished lighthouse test. The game expects the party to recognize that he is asking for assistance without directly stating the request.

Use the following dialogue route when speaking with him:

1

Enter Varenne Lighthouse

Travel to Varenne Lighthouse and climb to the top floor. Vogt is stationed inside the lighthouse rather than outside near the entrance.

2

Speak with Vogt

Talk to Vogt and listen through his explanation about the replacement components and the unfinished test run.

3

Choose the Helpful Response

Select “Is there something you need done?” This response acknowledges his indirect request and unlocks the lighthouse task.

4

Inspect the Bookcase

Read the lighthouse manual on the nearby shelf. The manual provides the operating order for the control panels.

5

Return to the Controls

Operate the panels using the low, mid, and high settings described in the next section.

Dialogue ChoiceResult
“Is there something you need done?”Starts the hidden Lighthouse Test Run quest
“Take care of yourself, okay?”Ends the conversation without starting the quest
Reading the manualReveals the lighthouse operating instructions
Asking about additional help afterwardAdds the optional BP bonus

The incorrect dialogue choice is especially important because the quest does not simply restart through another conversation. If the task fails to activate, check the dialogue response before trying the control panels.

Correct Trigger

The required response is “Is there something you need done?” Choose it before leaving Vogt’s conversation.

Lighthouse control panel sequence

The lighthouse puzzle is a short control-panel sequence involving two adjustable settings, an activation switch, and a connection control. The safest approach is to change the settings in order instead of experimenting with individual switches.

The required sequence is:

OrderControlSetting
1Orbal AmplitudeLow
2Stabilizer StrengthLow
3Activation SwitchOn
4Orbal AmplitudeMid
5Stabilizer StrengthMid
6Orbal AmplitudeHigh
7Stabilizer StrengthHigh
8Connection QuartzOn
Sequence Matters

Set the two adjustable controls together at each stage. Start with both at Low, move both to Mid, then move both to High before turning Connection Quartz on.

The controls are easiest to understand as three power stages:

Low Stage

Set Orbal Amplitude to Low, then set Stabilizer Strength to Low.

Mid Stage

Set Orbal Amplitude to Mid, then set Stabilizer Strength to Mid.

High Stage

Set Orbal Amplitude to High, then set Stabilizer Strength to High, then activate Connection Quartz.

Avoid switching the activation control too early or changing only one of the paired settings. If the puzzle does not complete, compare every panel against the sequence rather than repeating the final switch.

Fast Input Method

Think of the puzzle as Low/Low → Activation On → Mid/Mid → High/High → Connection Quartz On. This condensed pattern is easier to remember than the full panel list.

Once the final control is activated, the lighthouse begins its test run. The system should stop automatically after the test is complete, allowing you to return to Vogt.

Bonus BP, reward, and quest completion

After the lighthouse completes its test, speak with Vogt again. He will acknowledge the help and offer a reward connected to fishing. The most important completion detail is the final follow-up dialogue.

Choose the response equivalent to “Anything else we can do for you?” This adds +1 BP and completes the optional bonus objective.

Completion ActionOutcome
Finish the control-panel sequenceLighthouse test run succeeds
Speak with Vogt againQuest completion dialogue begins
Ask about additional assistance+1 BP bonus
Accept Vogt’s thanksReceive fishing bait
Leave the lighthouseQuest is finished

The reward is useful for the fishing system, but the bonus BP is the main reason to complete the final conversation carefully. Missing the follow-up question can reduce the quest’s total BP value even if the lighthouse itself was operated correctly.

Lighthouse Test Run Checklist:

  • Reach Varenne Lighthouse during Chapter 1
  • Speak with Vogt at the top floor
  • Choose “Is there something you need done?”
  • Read the manual and complete the Low/Mid/High sequence
  • Ask whether anything else can be done for the +1 BP bonus
Full-Credit Route

For the best result, start the hidden quest, complete every control-panel stage, return to Vogt, and ask about additional work before leaving.

Timing tips and common mistakes

The Lighthouse Test Run is easy once activated, but several details can cause players to miss it. The quest is tied to Chapter 1 and expires after leaving for Zeiss at the beginning of Chapter 2.

Use this comparison to identify the most common problems:

ProblemLikely CauseRecommended Fix
Vogt does not give the taskWrong dialogue responseSpeak with him again and choose the helpful request option
Control panels seem confusingManual was not inspectedRead the book on the nearby shelf
Test does not completeSettings changed out of orderRestart the sequence from Low/Low
BP total is lower than expectedFinal follow-up was skippedAsk whether anything else can be done
Quest is unavailable laterChapter deadline passedComplete it before the Chapter 2 transition

The manual is worth reading even if you already know the sequence. It confirms the intended operation and helps prevent accidental panel changes. The quest is designed as a small environmental task rather than a combat encounter, so preparation is mostly about timing and dialogue.

Before Leaving Chapter 1

Check your quest progress before traveling to Zeiss. The Lighthouse Test Run should be completed while the Chapter 1 investigation is still active.

A reliable route is to handle the lighthouse immediately after the quest becomes available. This reduces the chance of advancing the story past the deadline and keeps the optional BP reward available.
