Avenge the Circle — overviewSpoilers

Avenge the Circle is an Act 1 Underdark quest centered on the struggle for control of the myconid colony.

Avenge the Circle, also referred to as Avenge the Circle of Glot, begins in the Underdark after you have engaged with the myconid colony and encountered the Duergar near the lake. The quest concerns Glut, a deposed myconid sovereign who wants the Duergar threat removed and his former position restored. Its central conflict is not simply a battle against an outside enemy: it is also a dispute over who should lead the myconid community.

The quest asks you to decide whether to support Spaw, the colony’s current leader, or help Glut overthrow him. Glut can become involved in the confrontation, but his presence creates an important tactical complication because the Duergar react immediately if he is brought too close before the fight begins. Keeping him at a distance until combat starts is therefore part of managing the encounter rather than a cosmetic party choice.

The result of the conflict determines which myconid leader remains in power within the colony. That decision can alter the quest’s outcome and the rewards associated with it, so players seeking a particular resolution should save before committing to a side. The available source material does not establish a complete item-by-item reward table, exact enemy count, or a fixed route through the Underdark, so those details should not be treated as universal requirements.

WalkthroughSpoilers

  1. 01

    Establish the colony’s situation

    Speak with Spaw at the myconid colony

    Begin by talking to Spaw, the current leader of the myconid colony in the Underdark. This establishes the colony’s perspective and is the usual starting point for the quest; do not treat Glut’s later request as an independent conflict with no connection to Spaw.

    Location: Myconid colony, Underdark

    TipListen to both myconid leaders before making the political choice, especially if you want to compare the two possible resolutions.

  2. 02

    Identify the invading Duergar

    Travel toward the lake and encounter the Duergar

    Move from the colony toward the nearby lake and locate the Duergar group involved in the conflict. The group is led by Gekh Ugolek, who may also draw the party into a separate matter involving missing boots, so keep the two quest threads distinct in your journal and dialogue choices.

    Location: Lake near the myconid colony, Underdark

    Watch outThe available source material does not establish a single mandatory approach route or a fixed enemy count, so avoid relying on an unverified patrol number or exact map path.

  3. 03

    Decide whether Glut’s claim is worth supporting

    Hear Glut’s request

    After the conflict has been established, speak with Glut, the deposed myconid sovereign. Glut asks you to reclaim his home by killing the Duergar invaders, but helping him is also a challenge to Spaw’s authority rather than a neutral request for assistance.

    Location: Myconid colony, Underdark

    TipMake a manual save before accepting the leadership consequences if you want to examine both branches without replaying the entire Underdark section.

  4. 04

    Resolve the succession conflict

    Choose your side in the myconid dispute

    At the decisive point, support Spaw or help Glut overthrow him. This is the quest’s defining choice: it determines which myconid leader remains in power, so do not select dialogue casually if you are pursuing a specific colony outcome.

    Location: Myconid colony, Underdark

    Watch outThe leadership result is branch-sensitive and cannot be treated as a purely temporary dialogue decision.

    Missable
  5. 05

    Prepare the confrontation without triggering an unwanted reaction

    Position Glut safely before combat

    If Glut joins the party for the battle, keep him at a distance from the Duergar while you prepare. The Duergar react instantly when Glut is brought close before the fight begins, so separate him from the enemy until combat has actually started.

    Location: Duergar encounter area near the lake

    TipUse the party’s spacing to control when the confrontation begins; Glut should not be the character who approaches the Duergar first.

  6. 06

    Kill the Duergar invaders

    Defeat the Duergar invaders

    Fight the Duergar group associated with Gekh Ugolek and complete the hostile encounter. The supplied facts identify the Duergar as the invaders to be killed, but do not confirm a universal enemy roster, count, arena layout, or required attack order.

    Location: Lake area near the myconid colony

    Watch outBecause the source pack does not document every combat failure state, use normal party-survival precautions and avoid assuming that an unrecorded NPC can be protected indefinitely.

    Checkpoint
  7. 07

    Confirm the new myconid leadership

    Return to the colony and confirm the outcome

    Once the Duergar threat has been dealt with, return to the myconid colony and review the result of your chosen alliance. The quest resolves around the leader who remains in power, with outcomes and possible rewards varying according to whether you supported Spaw or Glut.

    Location: Myconid colony, Underdark

Mission mechanics

Avenge the Circle combines a combat objective with a faction decision. The Duergar are the immediate enemy, but the quest’s broader mechanic is that removing them does not by itself settle the myconid dispute. Your alliance determines whether the existing leader, Spaw, is preserved or whether Glut’s attempted overthrow succeeds.

Glut’s participation changes how the encounter should be staged. If he joins your party, the Duergar react instantly when he comes too close before combat begins. Treat Glut as a character whose position matters: keep him back during the approach, then bring him into the fight after hostilities have started.

Gekh Ugolek’s presence can make the area feel like a junction between quests because he may also involve the party in a separate missing-boots quest. The available material confirms that connection but does not provide enough information to document the separate quest’s full objectives here.

What works and what does not

Strengths

  • The quest gives the Underdark’s myconid and Duergar conflict a clear political consequence rather than treating the battle as an isolated encounter.
  • The Spaw-versus-Glut decision creates a meaningful branch in the colony’s leadership.
  • Glut’s proximity reaction gives the approach to combat a positioning consideration before the first attack.

Weaknesses

  • The quest’s reward outcome is dependent on the chosen side, making an unplanned dialogue choice difficult to undo without a prior save.
  • The area can overlap with Gekh Ugolek’s separate missing-boots storyline, which may make the local quest flow less obvious.
  • Exact enemy composition, enemy count, and a complete reward list are not established by the supplied material.

Best uses

  • Complete it when you are already resolving the Underdark’s myconid and Duergar storyline.
  • Make the leadership choice only after deciding which colony outcome you want.
  • Use party positioning to keep Glut away from the Duergar until combat begins.

Encounter phases

  1. 1

    Approach and identification

    Starts: The party reaches the lake area and encounters the Duergar.

    The Duergar group led by Gekh Ugolek represents the invading force connected to the myconid conflict.

    • Do not assume the separate missing-boots matter and Avenge the Circle are identical objectives.
    • If Glut is present, keep him away from the Duergar during this phase.
  2. 2

    Pre-combat positioning

    Starts: Glut joins the party or is brought into the confrontation before combat begins.

    Glut’s proximity can cause the Duergar to react instantly, so the party must control spacing before initiating the battle.

    • Immediate hostile reactionTell The Duergar react when Glut is brought too close before the fight begins.Answer Keep Glut at a distance until combat has started.
    • Approach with characters other than Glut while leaving him out of the Duergar’s immediate reach.
    • Use a save before the approach if you are testing the encounter setup.
  3. 3

    Duergar confrontation

    Starts: Combat begins against the invading group.

    Defeat the Duergar and complete the combat portion of Glut’s request to reclaim his home.

    • The source pack does not confirm a fixed enemy roster or count, so adapt to the actual group in your playthrough.
    • Keep the chosen faction objective in mind; victory alone does not describe the final leadership result.
  4. 4

    Leadership resolution

    Starts: The Duergar threat has been dealt with and the party returns to the colony.

    The side chosen in the dispute determines which myconid leader remains in power.

    • Review the consequences after the battle rather than assuming the colony’s leadership is unchanged.
    • Rewards and outcomes vary according to the Spaw or Glut branch.

Choices and consequencesSpoilers

  • Support Spaw

    You side with the current myconid leader, preserving Spaw’s claim in the colony’s internal power struggle.

    Spoiler
  • Help Glut overthrow Spaw

    You support the deposed myconid sovereign’s attempt to reclaim his home and change who remains in power.

    Spoiler
  • Bring Glut close to the Duergar before combat begins

    The Duergar react instantly, changing the timing of the encounter and potentially starting the confrontation before you are ready.

  • Resolve the conflict without committing to a preferred branch

    The supplied material does not document a neutral resolution that avoids the leadership choice; treat the quest as a branch-sensitive decision.

Failure conditions

  • Bring Glut too close to the Duergar before combat beginsThe Duergar react instantly to Glut’s presence at close range, so the confrontation can begin before the party is positioned as intended.
  • Choose the unintended myconid factionThe quest’s major political outcome is determined by whether you support Spaw or help Glut. A choice made without a save may require replaying the sequence to change it.

On failure

The available source material does not document every possible quest failure state, companion death state, or reset behavior. Treat the listed conditions as the confirmed risks rather than a complete technical failure table.

RewardsSpoilers

  • Quest resolution
    The conflict concludes with one myconid leader remaining in power.
  • Branch-dependent rewards
    Potential rewards vary depending on whether you support Spaw or Glut; the supplied material does not provide a verified item-by-item list.
  • Access to the quest outcome
    Completing the Duergar confrontation and resolving the leadership dispute determines the quest’s final state.

AftermathSpoilers

The colony’s leadership is decided by your alliance

Avenge the Circle does not end with the Duergar’s defeat alone. Supporting Spaw or helping Glut overthrow him determines which myconid leader remains in power, and the associated outcomes and possible rewards vary between those branches.

Trivia

  • The quest is also referred to as Avenge the Circle of Glot.
  • Glut’s request is framed around reclaiming his home, connecting the Duergar battle to his loss of status as myconid sovereign.
  • Gekh Ugolek can connect this area to a separate quest involving missing boots.
