Defeat the Duergar Intruders overview

Defeat the Duergar Intruders is an Act 1 side quest in Baldur's Gate 3 that begins at the Myconid Colony and sends the party into the Decrepit Village to deal with hostile Duergar.

The quest starts when the party speaks with Sovereign Spaw at the Myconid Colony in the Underdark. Spaw identifies the Duergar as a threat and asks the party to travel to the Decrepit Village, where the intruders have been causing trouble. The objective is direct, but the encounter can be dangerous if the party reaches it before it is prepared for a difficult fight.

The Decrepit Village is the central destination for this task, and the quest is resolved through combat rather than by simply investigating the Duergar presence. Players should treat the approach as a battle setup: position the party carefully, make use of high ground when possible, and avoid beginning the engagement from a tactically disadvantaged position. The supplied guidance commonly recommends reaching level 5 or higher before attempting the fight.

After the Duergar have been defeated, the party can return to Sovereign Spaw at the Myconid Colony and report the result. Completing the task earns Spaw’s reward, including access to the colony’s treasure room, and can also open the way to further questlines connected with the Myconid Colony and its visitors.

Glut may appear during this sequence and can offer to accompany the party against the Duergar. His offer gives the player an additional decision to consider before the battle, but the supplied sources do not establish every consequence of accepting or refusing his help. Treat that part of the quest as a choice point rather than assuming that every possible outcome is documented here.

Walkthrough

  1. 01

    Initiate the quest with Sovereign Spaw.

    Speak with Sovereign Spaw

    Go to the Myconid Colony and speak with Sovereign Spaw to start Defeat the Duergar Intruders. Listen for the request concerning the Duergar, because this conversation establishes the Decrepit Village as the place where the party must act.

    Location: Myconid Colony

    TipIf the quest is not active, confirm that the conversation with Sovereign Spaw has been completed before leaving the colony.

  2. 02

    Choose a suitable time to attempt the battle.

    Prepare the party for the journey

    Before travelling to the Decrepit Village, make sure the party is ready for a combat encounter that is commonly regarded as challenging. The supplied advice recommends being level 5 or higher, although this is guidance rather than a confirmed mandatory threshold.

    Location: Myconid Colony

    Watch outStarting the encounter while underprepared can make the fight substantially more difficult.

  3. 03

    Reach the area occupied by the Duergar intruders.

    Travel to the Decrepit Village

    Leave the Myconid Colony and make your way to the Decrepit Village in the Underdark. The supplied sources identify the village as the destination, but do not establish a single required entrance or route, so avoid relying on an undocumented approach.

    Location: Underdark; Decrepit Village

    TipSave before entering the village so that you can retry the opening position if the first engagement goes badly.

    Checkpoint
  4. 04

    Find a defensible position before the fight.

    Survey the battlefield

    Look over the Decrepit Village before committing the party to combat and identify any available high ground. Tactical advice for this encounter emphasizes using elevation to avoid disadvantages, so do not rush into the fight without considering where each party member will begin.

    Location: Decrepit Village

    Watch outThe available sources do not confirm the village’s exact layout, so this guide cannot name a specific ladder, roof or entrance.

  5. 05

    Resolve the available assistance choice.

    Decide whether to accept Glut’s help

    Glut may offer to accompany the party to help defeat the Duergar. Consider the offer before beginning the main engagement, since accepting or refusing assistance can affect how you want to approach the encounter; the supplied sources do not document every consequence.

    Location: Underdark; Decrepit Village

    TipTreat Glut’s offer as optional unless the game’s current quest state explicitly makes it part of your objective.

  6. 06

    Begin combat from a favorable position.

    Use high ground when the fight begins

    Open the battle from elevated terrain when the village provides a suitable position, keeping the party spread enough to avoid allowing the enemy to exploit one clustered group. The important tactical principle established by the available guidance is to use high ground to reduce disadvantages during the encounter.

    Location: Decrepit Village

    Watch outThe sources do not provide a reliable enemy count or a complete list of Duergar abilities, so adapt the opening to the enemies actually present in your game.

  7. 07

    Slay the Duergar causing trouble.

    Defeat the Duergar intruders

    Fight the Duergar in the Decrepit Village until the quest objective to slay the intruders is complete. Maintain the advantage created by your initial position and avoid abandoning a safe elevation without a clear reason, since the encounter is considered difficult.

    Location: Decrepit Village

    Watch outIf the party is defeated, the combat attempt fails and must be retried from a previous save or checkpoint.

  8. 08

    Verify completion of the battle stage.

    Confirm that the combat objective is complete

    After the fighting ends, check that the Duergar threat has been cleared and that the quest has advanced beyond the defeat objective. Do not leave the Underdark assuming the task is finished until the game recognizes the successful outcome.

    Location: Decrepit Village

    TipUse the post-combat pause to heal, regroup and review the quest log before returning to the colony.

  9. 09

    Report the victory to Sovereign Spaw.

    Return to Sovereign Spaw

    Travel back to the Myconid Colony and speak with Sovereign Spaw after defeating the intruders. Reporting the result is the step that resolves the request and allows Spaw to provide the associated reward.

    Location: Myconid Colony

    Checkpoint
  10. 10

    Claim the reward and check for follow-up content.

    Collect the quest reward

    Complete the follow-up conversation with Sovereign Spaw to receive the reward for dealing with the Duergar. Completion includes access to the colony’s treasure room, and the outcome may also unlock further questlines connected with the colony.

    Location: Myconid Colony

Mission mechanics

This quest is built around a clear travel-and-combat loop. Sovereign Spaw sends the party from the Myconid Colony to the Decrepit Village, where the Duergar must be defeated, before the party returns to the colony to report the result. There is no supplied evidence that the objective can be completed by merely negotiating with or bypassing the intruders.

Positioning is the main tactical consideration identified in the available material. High ground can help the party avoid disadvantages during the battle, making the approach to the village important even though the objective itself is simply to defeat the enemies. The exact terrain features and enemy composition are not confirmed by the source pack, so the party should assess the battlefield rather than follow an assumed route.

Glut adds a possible companion decision to the sequence. The sources establish that Glut may offer to accompany the party, but they do not provide a complete rules explanation for the offer or a definitive account of every resulting branch. Players seeking a particular outcome should record their save before deciding.

What works and what does not

Strengths

  • The objective is easy to understand: receive the request, reach the Decrepit Village, defeat the Duergar and return to Sovereign Spaw.
  • The quest gives the player a meaningful battlefield consideration by rewarding attention to high ground and opening position.
  • The reward has practical exploration value because completion includes access to the Myconid Colony’s treasure room.
  • Glut’s possible involvement adds a decision point without changing the quest’s central combat objective.

Weaknesses

  • The encounter is often considered challenging, especially for parties attempting it before the commonly recommended level 5 threshold.
  • The supplied material does not identify a fixed enemy count, so players cannot plan around a confirmed number of opponents from this guide alone.
  • The consequences of accepting or refusing Glut’s offer are not fully established in the available sources.

Best uses

  • Approach the village as a prepared combat mission rather than an improvised fight.
  • Use high ground where available and make the opening position part of the battle plan.
  • Return to the Myconid Colony after the victory instead of treating the enemy defeat as the final step.

Encounter phases

  1. 1

    Approach and setup

    Starts: The party reaches the Decrepit Village before initiating the main fight.

    Use the approach to assess the terrain and select a favorable position. High ground is the principal tactic identified by the supplied guidance.

    • Do not rush directly into combat if a safer elevated position is available.
    • Save before the engagement so that a poor opening can be retried.
  2. 2

    Duergar engagement

    Starts: The party begins combat with the intruders.

    Defeat the Duergar while preserving the positional advantage established during setup. The source pack does not confirm a complete enemy roster or a fixed number of opponents.

    • Expect the encounter to punish underprepared parties; level 5 or higher is commonly recommended.
  3. 3

    Resolution and return

    Starts: The Duergar have been defeated and the combat objective is complete.

    Confirm the quest has advanced, then return to Sovereign Spaw at the Myconid Colony. The reward and access to the colony’s treasure room are obtained through this report-back stage.

    • Heal and regroup before travelling back.
    • Speak with Sovereign Spaw again rather than ending the quest at the village.

Choices and consequencesSpoilers

  • Accept Glut’s offer to accompany the party.

    Glut can accompany the party to help defeat the Duergar. The supplied sources do not establish all later consequences of accepting the offer.

  • Decline Glut’s offer.

    The party proceeds without the assistance offered by Glut. The available material does not document every consequence of refusing.

  • Return to Sovereign Spaw after the battle.

    Reporting the victory resolves the task, provides Spaw’s reward and includes access to the colony’s treasure room.
