Cure the Poisoned Gnome

Cure the Poisoned Gnome is a short, time-sensitive rescue quest in Act One of Baldur's Gate 3. Thulla, a poisoned deep gnome, is found at the Myconid Colony in the Underdark, and the party must provide an effective remedy before the situation advances or expires.

The quest is built around a straightforward medical problem rather than a conventional combat encounter. Thulla can be saved with an Antitoxin, a standard Antidote, the Duergar Antidote obtained from Gekh Coal, or the Lesser Restoration spell. The game accepts these as different solutions to the same immediate objective, so the party can use its supplies, spells, or knowledge of the surrounding Underdark situation.

This is a missable quest. Long rests can cause the situation to progress or expire, and leaving Thulla untreated for too long may result in her death. Because the outcome affects access to the related Save the Grymforge Gnomes questline, players who want to preserve the opportunity should investigate Thulla promptly rather than treating the encounter as a permanent colony activity.

A successful cure rewards the Boots of Speed and also initiates Save the Grymforge Gnomes. The quest therefore has value beyond its immediate reward: it establishes Thulla as a rescued deep gnome and connects the Myconid Colony portion of the Underdark to the later Grymforge-related storyline. The available source material does not establish a precise long-rest count or a single mandatory route to the cure.

WalkthroughSpoilers

  1. 01

    Find the quest location

    Reach the Myconid Colony

    Travel into the Underdark and make your way to the Myconid Colony, the location associated with Thulla's rescue. The supplied material does not identify a single required entrance or route, so use the path available in your playthrough.

    Location: Myconid Colony

    TipBegin looking for Thulla as soon as you reach the colony instead of spending several long rests on unrelated activities.

  2. 02

    Identify the poisoned gnome

    Speak with Thulla

    Locate Thulla, the poisoned deep gnome, and interact with her to begin addressing the problem. Her condition is the focus of this quest, so do not leave the colony assuming the rescue will remain available indefinitely.

    Location: Myconid Colony

    Watch outThe quest can progress or expire after a number of long rests, and the precise threshold is not established in the supplied material.

  3. 03

    Cure the poisoning

    Choose an available remedy

    Use an Antitoxin or a standard Antidote on Thulla, or cast Lesser Restoration if that spell is available to the party. These are direct solutions that avoid needing the Duergar-specific option.

    Location: Myconid Colony

    TipCheck the party's consumables and prepared spells before leaving the colony so that an available remedy is not overlooked.

  4. 04

    Secure an alternative cure

    Obtain the Duergar Antidote if needed

    If the party does not have an Antitoxin, standard Antidote, or Lesser Restoration, the Duergar Antidote found on Gekh Coal is another stated solution. The supplied material does not specify every acquisition step, so confirm the item is available before committing to further delays.

    Location: Underdark

    Watch outDo not assume that waiting for a different solution is harmless; additional long rests can affect the quest.

  5. 05

    Resolve the quest

    Complete the rescue and follow the aftermath

    After Thulla is successfully cured, collect the Boots of Speed and note that Save the Grymforge Gnomes is initiated. If Thulla is not healed in time, she may die and the related questline opportunity can be missed.

    Location: Myconid Colony

Mission mechanics

This quest uses a remedy check rather than a stated combat challenge. The important mechanic is having one accepted treatment available when the party reaches Thulla: an Antitoxin, a standard Antidote, the Duergar Antidote associated with Gekh Coal, or Lesser Restoration can serve that purpose.

Timing is the other defining mechanic. The quest may progress or expire after a certain number of long rests, although the supplied material does not provide a reliable exact count. Treat the rescue as active once discovered and avoid assuming that the colony will preserve Thulla's condition while the party pursues distant objectives.

The cure also has a progression effect. It is not merely a health intervention: successful completion grants the Boots of Speed and initiates Save the Grymforge Gnomes, making the interaction a bridge between the immediate Myconid Colony situation and a connected gnome storyline.

What works and what does not

Strengths

  • The quest offers multiple valid cures, allowing players to use either consumables, a spell, or the Duergar Antidote route.
  • Its objective is clear once Thulla is found: remove the poisoning before the time-sensitive state is lost.
  • The reward also advances a related questline, giving the rescue narrative significance beyond the immediate item.

Weaknesses

  • The time-sensitive nature can punish players who take several long rests without checking on Thulla.
  • The supplied material does not establish an exact expiration threshold, making it difficult to plan around a precise number of rests.
  • Players without a cure prepared may need to locate an alternative remedy while the quest remains vulnerable to progression.

Best uses

  • Treat it as an early Underdark priority after finding the Myconid Colony.
  • Keep more than one possible remedy in mind rather than relying on a single consumable.
  • Complete the rescue before committing to extended rest-based preparation or exploration.

Choices and consequencesSpoilers

  • Use an Antitoxin

    Thulla can be saved, allowing the party to complete the rescue and receive the Boots of Speed.

  • Use a standard Antidote

    This is another stated cure for Thulla's poisoning and can lead to the successful rescue outcome.

  • Cast Lesser Restoration

    The spell can remove the poisoning and resolve the immediate medical problem.

  • Use the Duergar Antidote found on Gekh Coal

    This alternative remedy can also save Thulla and preserve the related quest progression.

  • Delay through too many long rests

    The quest may progress or expire; Thulla may die, and the related questline opportunity can be missed.

AftermathSpoilers

Trivia

  • The quest can be solved through either consumable remedies or the Lesser Restoration spell.
  • The Duergar Antidote provides a solution tied to Gekh Coal rather than requiring the party to rely only on a generic Antitoxin or Antidote.
  • Curing Thulla serves both a medical purpose and a quest-progression purpose by initiating Save the Grymforge Gnomes.
