Key takeaways

The investigation is advanced by reading specific records and opening a concealed route, not by following a single obvious objective marker.

  • Start with the Potter's Chest Read the note inside the Potter's Chest in the abandoned Potter's Workshop. Finding the workshop without examining the chest does not provide the clue that begins the investigation.
  • Search the Last Light Inn cellar The cellar contains Meenlocks and a Selûnite altar. Defeating the creatures and locating the altar supplies the next important piece of evidence.
  • Get the Tower-shaped Key Mattis at the Last Light Inn can provide the Tower-shaped Key. Keep it available because it opens the hidden route connected to the Keyholed Herald in the Masons' Guild.
  • Read the Mason's Log The Mason's Log is the decisive record in the secret area of the Masons' Guild. Reading it completes the primary objectives and explains the resistance's opposition to Ketheric Thorm and Sharran influence.

Find the Selunite Resistance Hideout

Follow a chain of hidden records through the Shadow-Cursed Lands to learn what happened to the Selûnite Resistance.

Find the Selunite Resistance Hideout is an Act 2 side quest in Baldur's Gate 3. It begins when the party reads a note found inside a Potter's Chest in the abandoned Potter's Workshop, turning an otherwise easily overlooked location into the starting point for an investigation into the region's past.

The quest sends the party to two important locations: the cellar beneath the Last Light Inn and the Masons' Guild. In the cellar, Meenlocks guard a Selûnite altar that provides another clue. The investigation then depends on obtaining the Tower-shaped Key from Mattis at the Last Light Inn and using it to open a concealed route in the Masons' Guild.

The final evidence is the Mason's Log, found in a secret area of the Masons' Guild after the party deals with shadows and a wraith. Reading the log completes the primary quest objectives and adds historical context about opposition to Ketheric Thorm and Sharran influence in Reithwin.

This is primarily an exploration and lore quest rather than a mission built around a single named boss. Its important progression points are easy to overlook: the note in the Potter's Chest, the Selûnite altar, the Tower-shaped Key, the Keyholed Herald, and the Mason's Log.

Walkthrough

  1. 01

    Find the note that starts the investigation.

    Search the abandoned Potter's Workshop

    Travel to the abandoned Potter's Workshop in Act 2 and inspect its containers rather than stopping after entering the building. The relevant clue is a note found inside the Potter's Chest, and reading that note begins the investigation.

    Location: abandoned Potter's Workshop

    TipIf the quest does not appear to advance, check the Potter's Chest itself and read the note inside it.

  2. 02

    Investigate the Selûnite Resistance.

    Read the note in the Potter's Chest

    Interact with the Potter's Chest and read the note recovered from it. This is the quest's initiating evidence, so leaving the note unread can make the later objectives appear disconnected.

    Location: abandoned Potter's Workshop

    Watch outThe source material does not establish whether the note can be permanently missed, so inspect it before leaving the workshop.

    Checkpoint
  3. 03

    Explore the cellar for further evidence.

    Enter the Last Light Inn cellar

    Continue the investigation at the Last Light Inn by searching its cellar. The cellar is not just a lore stop: Meenlocks occupy the area, and the party must deal with them before safely examining the clue associated with the Selûnite Resistance.

    Location: Last Light Inn cellar

    TipTreat the cellar as both an encounter area and an investigation location; search it after the fight rather than immediately moving on.

  4. 04

    Remove the threat blocking the investigation.

    Defeat the Meenlocks

    Clear the Meenlocks encountered in the Last Light Inn cellar. The supplied facts identify these creatures as the enemies in the cellar but do not establish their number, exact placement, or a special combat pattern.

    Location: Last Light Inn cellar

    Watch outDo not assume the cellar clue has been collected when the combat ends; the Selûnite altar still needs to be located.

    Checkpoint
  5. 05

    Find the next resistance clue.

    Locate the Selûnite altar

    Search the cleared cellar for the Selûnite altar and examine it as part of the investigation. Finding the altar provides further clues and connects the cellar sequence to the broader history of the resistance.

    Location: Last Light Inn cellar

    TipAfter the Meenlocks are defeated, perform a deliberate search of the cellar instead of leaving as soon as the combat ends.

  6. 06

    Acquire the key for the hidden passage.

    Speak with Mattis about the Tower-shaped Key

    At the Last Light Inn, locate Mattis and obtain the Tower-shaped Key. The key is the quest's essential access item for the Masons' Guild, so keep track of it before beginning the next stage of the investigation.

    Location: Last Light Inn

    Watch outThe supplied material does not specify dialogue requirements or alternate ways to obtain the key; do not rely on an unverified substitute.

    Checkpoint
  7. 07

    Find the entrance to the resistance evidence.

    Travel to the Masons' Guild

    Take the investigation to the Masons' Guild after obtaining the Tower-shaped Key. The guild contains the concealed route and the final record, so continue searching the site instead of treating it as an unrelated location.

    Location: Masons' Guild

    TipThe Keyholed Herald is the landmark associated with the secret passage; use it to orient the search.

  8. 08

    Access the secret area.

    Unlock the passage behind the Keyholed Herald

    Use the Tower-shaped Key to open the secret passage behind a Keyholed Herald within the Masons' Guild. This concealed route leads into the area where the final evidence is guarded.

    Location: Masons' Guild

    Watch outThe source identifies the passage's position relative to the Keyholed Herald but does not provide a more precise room description.

    Checkpoint
  9. 09

    Secure the room containing the Mason's Log.

    Defeat the shadows and the wraith

    Proceed through the secret area and overcome the shadows and a wraith that protect access to the Mason's Log. The source material does not specify their number or a required party strategy, so focus on clearing the area before attempting to read the record.

    Location: Masons' Guild secret area

    TipSearch the area after combat; the quest's completion evidence is a readable record rather than a separate boss reward.

    Checkpoint
  10. 10

    Complete the investigation.

    Read the Mason's Log

    Find and read the Mason's Log once the secret area is secure. This completes the primary quest objectives and supplies historical context about the resistance against Ketheric Thorm and the effect of Sharran influence in Reithwin.

    Location: Masons' Guild secret area

    Watch outReading the log is the stated completion action, so do not leave the secret area without examining it.

    Checkpoint
  11. 11

    Investigate the optional hidden chamber.

    Search for the hidden treasure chamber

    After securing the Mason's Guild area, look for the wall button that reveals a secret treasure chamber. The chamber is an additional discovery in the guild and is separate from the primary objective of reading the Mason's Log.

    Location: Masons' Guild

    TipThe source confirms a button on the wall but does not identify its exact position or list the chamber's contents.

Mission mechanics

This quest uses environmental investigation as its main progression system. The party must inspect a container, read a note, locate a specific altar, acquire a named key, identify a landmark, and finally read a log. Combat clears access to some clues, but defeating enemies alone does not complete the investigation.

The Tower-shaped Key is the central gating item. Mattis at the Last Light Inn provides it, and the key opens the secret passage behind a Keyholed Herald in the Masons' Guild. This makes the order of exploration important: reaching the guild before securing the key may reveal the relevant landmark without allowing the party to finish the route.

The optional treasure chamber adds another layer of environmental discovery. A button on a wall in the Masons' Guild reveals it, but the supplied information does not identify the chamber's contents. Readers should therefore treat the button as an exploration opportunity rather than a confirmed reward source.

What works and what does not

Strengths

  • Connects several easily overlooked Act 2 locations into a coherent investigation.
  • Uses readable records and environmental clues to reveal the history of the Selûnite Resistance.
  • Rewards careful exploration of the Last Light Inn cellar and Masons' Guild rather than simple objective-marker following.
  • Provides context about resistance to Ketheric Thorm and Sharran influence in Reithwin.

Weaknesses

  • The starting note is inside a specific container, so entering the Potter's Workshop without searching it can leave the quest undiscovered.
  • The quest's progression is dependent on finding and using the Tower-shaped Key.
  • The exact contents of the optional treasure chamber are not established in the supplied material.
  • Combat and location details beyond the named enemies and landmarks are not documented here.

Best uses

Failure conditions

  • Leaving the Potter's Workshop without reading the noteThe note inside the Potter's Chest is the stated starting point, so failing to inspect it can prevent the investigation from being initiated.
  • Leaving the cellar without locating the altarDefeating the Meenlocks is not the complete cellar objective; the Selûnite altar must also be found for the next clue.
  • Entering the Masons' Guild without the Tower-shaped KeyThe secret passage behind the Keyholed Herald is opened with the Tower-shaped Key obtained from Mattis.
  • Leaving the secret area without reading the Mason's LogThe log is the action that completes the primary objectives, so clearing the shadows and wraith is not sufficient by itself.

On failure
