Search the Cellar

Key takeaways

Keep these points in mind before entering the cellar.

• Start with the journal Read the Apprentice's Journal before treating the cellar as a complete exploration area; the journal is the quest's stated trigger.
• Search behind the cabinet The route onward is not presented as an ordinary doorway. Inspect the display cabinet area and pull the hidden lever behind it.
• Prepare for more than a basement The secret passage leads to a hidden laboratory with traps, an ornate mirror, and Undead Agile Guardians.
• The tome is the major decision Necromancy of Thay is the quest's key item, and the player must decide whether to unlock it for dark power or destroy it.

Search the Cellar

Search the Cellar turns a seemingly ordinary basement in the Blighted Village into an investigation of necromantic secrets.

Search the Cellar is an Act 1 quest in Baldur's Gate 3 that begins when the party reads the Apprentice's Journal. The journal can typically be discovered either in the Whispering Depths or in the apothecary within the Blighted Village, giving the party a reason to examine the settlement's cellar rather than treating it as a routine place to search. The quest's central purpose is to uncover what a local necromancer was hiding.

The investigation is built around exploration rather than a single conventional objective marker. In the cellar, the party must search the room carefully, locate a concealed lever behind a display cabinet, and use it to open the route into a secret passage. This makes positioning and observation important: simply checking the obvious containers does not reveal the full path, and the hidden mechanism is easy to overlook if the room is treated as a straight-line combat area.

Beyond the concealed passage lies a hidden laboratory containing traps, an ornate mirror, and a dangerous encounter with Undead Agile Guardians. The final major discovery is Necromancy of Thay, a sinister tome whose fate is determined by the player's choice. The quest therefore combines environmental investigation, hazardous traversal, combat, and a morally consequential decision without requiring the page to assume a particular character build or party composition.

WalkthroughSpoilers

1. 01

   Initiate Search the Cellar

   Read the Apprentice's Journal

   Find the Apprentice's Journal in the Whispering Depths or in the apothecary within the Blighted Village, then read it rather than merely collecting it. Reading the journal is what initiates Search the Cellar and points the investigation toward the settlement's hidden necromantic history.

   Location: Whispering Depths or the apothecary within the Blighted Village

   TipIf the quest has not appeared, confirm that the journal was opened and read, not just added to the inventory.

   Checkpoint
2. 02

   Investigate the cellar

   Enter and search the cellar

   Go to the cellar in the Blighted Village and examine the area as an investigation site. The important progression is concealed rather than presented as an obvious route, so check the room's fixtures and display furniture before leaving or assuming the cellar ends there.

   Location: Cellar beneath the Blighted Village

   Watch outDo not treat the first cellar room as the whole quest area; the passage onward is hidden.

3. 03

   Reveal the secret passage

   Find the lever behind the display cabinet

   Inspect the space behind the display cabinet and locate the hidden lever. Pulling it reveals the secret passage, which is the required transition from the cellar into the concealed section of the quest.

   Location: Cellar, behind the display cabinet

   TipSearch around the cabinet itself rather than focusing only on containers or the most visible doorway.

   Checkpoint
4. 04

   Reach the hidden laboratory

   Follow the secret passage

   Use the newly revealed route to leave the ordinary cellar area and proceed toward the hidden laboratory. Move carefully through the passage because the quest specifically includes traps, and rushing through an unexplored route can turn the transition into an avoidable hazard.

   Location: Secret passage beneath the cellar

   Watch outThe passage is part of the trapped exploration section; check the route before committing the whole party to it.

5. 05

   Explore the laboratory

   Navigate the laboratory and ornate mirror

   Continue through the hidden laboratory, dealing with its traps and interacting with the ornate mirror as the investigation requires. The mirror is a progression element in this section, so do not ignore environmental interactions while preparing for the encounter beyond it.

   Location: Hidden laboratory

   TipApproach the laboratory as a puzzle-and-hazard space before treating it as a simple arena.

   Checkpoint
6. 06

   Defeat or overcome the Undead Agile Guardians

   Survive the Undead Agile Guardians

   The laboratory contains a dangerous encounter with Undead Agile Guardians. Use the room and surrounding route deliberately, keep the party together while handling the threat, and avoid allowing the combat to distract you from the quest's final objective: dealing with the tome discovered in this area.

   Location: Hidden laboratory

   Watch outThe guardians are the principal combat danger identified for this quest; an unsuccessful fight can prevent safe access to the laboratory's discovery.

7. 07

   Handle Necromancy of Thay

   Decide the fate of Necromancy of Thay

   After reaching the relevant laboratory area, handle Necromancy of Thay by choosing whether to unlock the book for its dark power or destroy it to prevent further evil. This is the quest's major consequence point, so make the decision only after considering whether the party wants the tome's dark route or its destruction.

   Location: Hidden laboratory

   Watch outThe choice changes how the quest resolves; unlocking and destroying the tome are not the same outcome.

Mission mechanics

The cellar's main mechanic is environmental discovery. Progress does not come only from defeating enemies or opening containers: the party must identify the display cabinet as part of the puzzle and find the hidden lever behind it. That lever exposes the route into the secret passage, so careful inspection of the room is more valuable than moving directly toward the most obvious exit.

The laboratory changes the rhythm of the quest. It combines traps, an ornate mirror, and an undead encounter, requiring the party to alternate between cautious exploration and combat readiness. The source material does not establish the exact trap positions, activation rules, or mirror dialogue, so this guide recommends deliberate interaction without assigning unsupported solutions.

Necromancy of Thay provides the quest's most important non-combat mechanic: a decision about the fate of a named item. The player can pursue the tome's dark power or destroy it to prevent further evil. Because the source material does not specify every later gameplay effect, the choice should be described as a branch in the quest's resolution rather than as a promise of particular abilities or rewards.

What works and what does not

PhasesSpoilers

1. 1

   Laboratory approach

   Starts: Entering the route beyond the hidden cellar lever

   The party moves through the concealed section toward the laboratory while dealing with traps and the ornate mirror.

   • Explore slowly and treat environmental objects as possible progression elements.
   • Keep the party prepared for the transition from traversal to combat.
2. 2

   Undead Agile Guardians

   Starts: Reaching the dangerous encounter in the hidden laboratory

   Undead Agile Guardians defend the laboratory area and create the quest's main combat obstacle.

   • The supplied sources do not establish specific attack names, tells, or counters, so avoid relying on an undocumented boss pattern.
   • Use the surrounding exploration route deliberately and recover before proceeding to the tome.
3. 3

   Tome resolution

   Starts: Reaching Necromancy of Thay after the laboratory sequence

   The investigation culminates in deciding whether to unlock the tome for dark power or destroy it.

   • This is a decision phase rather than a conventional combat phase.
   • Consider the desired quest outcome before confirming the choice.
