Find the Missing Boots

Key takeaways

The quest is short in structure but easy to disrupt if you postpone the delivery or make the Duergar hostile.

Start with Gekh Coal Speak with Gekh Coal in the Underdark to begin the search and learn that Thulla has taken Sergeant Thrinn's boots.
Look in the Myconid Colony Thulla is located in the Myconid Colony and is suffering from Duergar poison, creating the quest's main recovery route.
Choose how to recover the boots Curing Thulla lets you receive the boots from her, while killing her lets you obtain them from her corpse instead. Recovery choice
Deliver before the situation changes Return the boots to Sergeant Thrinn at Grymforge before relevant story milestones or Duergar hostility make the handover impossible.
The reward is a selection Sergeant Thrinn offers a choice between the Bracing Band and the Armor of the Uninhibited Kushigo rather than granting both items.

Find the Missing Boots is an Act One side quest that moves between the Underdark's Duergar and Myconid communities.

The quest begins when you speak with Gekh Coal in the Underdark. He directs your attention toward a runaway deep gnome named Thulla, who has taken a pair of boots belonging to Sergeant Thrinn. The initial objective is therefore less about finding an item in a container and more about following the consequences of a dispute between the Duergar and a deep gnome who is trying to escape them.

Thulla can be found in the Myconid Colony, where she is suffering from Duergar poison. If you cure her, she can give you the missing boots, providing a nonviolent route through the central problem. The quest does not require you to resolve the situation in only one way: killing Thulla also allows the boots to be recovered by looting her corpse, but that decision changes the character outcome and removes the opportunity to help her.

With the boots in hand, the quest points you toward Grymforge and Sergeant Thrinn. Returning the item to Thrinn completes the delivery and opens a reward choice between the Bracing Band ring and the Armor of the Uninhibited Kushigo. Timing matters because later story milestones, or a hostile turn by the Duergar, can prevent the boots from being returned and can leave the quest incomplete.

WalkthroughSpoilers

01
Begin Find the Missing Boots
Speak with Gekh Coal
Travel through the Underdark until you find Gekh Coal and speak with him to initiate Find the Missing Boots. His account identifies Thulla as a runaway deep gnome and establishes that the missing item belongs to Sergeant Thrinn.
Location: Underdark
TipTreat this conversation as the starting point for the quest rather than searching for the boots first.
02
Find Thulla
Travel to the Myconid Colony
Go to the Myconid Colony after learning that Thulla is the person connected to the stolen boots. The quest's intended investigation leads there, and Thulla's condition is central to deciding whether you help her or take the item by force.
Location: Myconid Colony
Watch outDo not assume the quest can be safely postponed indefinitely; later story milestones can affect whether the boots can still be delivered.
03
Resolve Thulla's immediate situation
Speak with Thulla and assess the poison situation
Locate Thulla in the Myconid Colony and speak with her while she is suffering from Duergar poison. The conversation presents the opportunity to cure her, which is the route that allows her to remain alive and hand over the boots.
Location: Myconid Colony
Missable
04
Acquire Sergeant Thrinn's boots
Cure Thulla and receive the boots
Use the available cure for Thulla's Duergar poison, then obtain the boots from her as the reward for helping her. This completes the recovery portion without requiring you to kill the deep gnome.
Location: Myconid Colony
TipIf you want the nonlethal outcome, resolve Thulla's poison before taking any action that would kill her.
05
Recover the boots by looting Thulla's corpse
Use the violent alternative if you choose it
You can instead kill Thulla and loot her corpse to recover the boots. This obtains the quest item, but it is a different outcome from curing her and should be treated as an irreversible character choice for the encounter.
Location: Myconid Colony
Watch outKilling Thulla removes the option to cure her and receive the boots from her directly.
Missable
06
Find Sergeant Thrinn
Return to Grymforge
Once you have the boots, travel to Grymforge and locate Sergeant Thrinn. The quest cannot be finished merely by possessing the item; the required final action is to hand it back to its owner.
Location: Grymforge
Checkpoint
07
Complete the handover
Deliver the boots to Sergeant Thrinn
Speak with Sergeant Thrinn and return the boots. If the Duergar have not become hostile and the relevant story milestones have not passed, this completes the delivery and leads to the quest reward selection.
Location: Grymforge
Watch outIf the Duergar turn hostile, or if a relevant story milestone has already occurred, returning the boots may no longer be possible.
08
Claim one reward
Choose the quest reward
After the handover, select one of the two offered rewards: the Bracing Band ring or the Armor of the Uninhibited Kushigo. The reward choice is the final reported outcome of Find the Missing Boots.
Location: Grymforge

Mission mechanics

Find the Missing Boots is structured around possession and delivery rather than a conventional combat objective. The quest begins with information from Gekh Coal, redirects the player to Thulla in the Myconid Colony, and ends only when the recovered boots are returned to Sergeant Thrinn at Grymforge.

The central mechanic is the split recovery route. Helping Thulla by curing her Duergar poison produces the boots through a conversation-based outcome. A player who chooses to kill her can still obtain the boots by looting her corpse, but that route changes the result for Thulla and cannot be treated as an equivalent peaceful resolution.

Quest availability is also state-dependent. The source material warns that certain story milestones and Duergar hostility can make the return impossible, so the safest approach is to complete the handover once the boots have been recovered instead of carrying them while advancing unrelated Underdark events.

What works and what does not

Strengths

The quest supports both a helping route and a lethal recovery route, allowing the player to decide Thulla's immediate fate.
Its locations and objectives are clearly divided between the Myconid Colony and Grymforge.
The final reward is a meaningful item choice rather than an automatic grant of both options.

Weaknesses

The quest can become impossible to complete after certain story milestones, making timing important.
Duergar hostility can block the final delivery even when the player has already recovered the boots.
The lethal route obtains the item but prevents the player from resolving Thulla's poison by helping her.

Best uses

Complete it while the Underdark's Duergar situation remains stable.
Choose the recovery route that matches the intended outcome for Thulla before moving on to the final delivery.
Review the two reward names before speaking to Sergeant Thrinn if the equipment choice matters to the party.

Choices and consequencesSpoilers

Cure Thulla's Duergar poison.
Thulla survives the immediate situation and gives you Sergeant Thrinn's boots as a reward for helping her.
Kill Thulla and loot her corpse.
You can still obtain the boots, but Thulla is dead and the nonviolent recovery outcome is no longer available.
Spoiler
Return the boots to Sergeant Thrinn before the Duergar turn hostile or relevant story milestones pass.
The delivery remains possible and you can choose the quest reward.
Delay the return until after a blocking story change.
The boots may no longer be returnable, leaving the quest impossible to complete in that state.
Spoiler
Choose the Bracing Band.
You receive the ring instead of the Armor of the Uninhibited Kushigo.
Choose the Armor of the Uninhibited Kushigo.
You receive the armor instead of the Bracing Band.

Collectibles and secrets

01
Sergeant Thrinn's boots
Where: Thulla in the Myconid Colony or Thulla's corpse
This is the quest item required for the final handover to Sergeant Thrinn. It can be received after curing Thulla or recovered by looting her corpse if she is killed.
Missable

Failure conditionsSpoilers

A relevant story milestone passes before the boots are returned.The quest can become impossible to complete if the player waits beyond certain story progression points.
The Duergar turn hostile.Hostility can make returning the boots to Sergeant Thrinn impossible even if the item has already been recovered.
Thulla is killed before the player intends to pursue the lethal route.The player loses the option to cure her and must rely on looting her corpse for the boots.

On failure

After recovering the boots, completing the delivery promptly is the safest way to avoid a state change that blocks the quest.

RewardsSpoilers

Bracing Band
One of the two rewards offered by Sergeant Thrinn when the boots are returned.
Armor of the Uninhibited Kushigo
The alternative reward offered by Sergeant Thrinn; the player chooses this or the Bracing Band.
Sergeant Thrinn's boots
The recovered quest item is delivered to Sergeant Thrinn rather than retained as the final reward.

AftermathSpoilers

Do not leave the delivery indefinitely

Once the boots are recovered, return them to Sergeant Thrinn before relevant story milestones or a hostile change among the Duergar makes the handover impossible. The final reward is selected at the delivery, so finishing the quest requires both possession of the boots and a successful conversation with Thrinn.

Trivia

The quest's title refers to boots that change hands between Thulla and Sergeant Thrinn rather than to a standard treasure hunt.
The boots can be recovered through either a cure-based outcome or by looting Thulla's corpse.
The reward choice connects the quest's small recovery objective to two distinct equipment options: the Bracing Band and the Armor of the Uninhibited Kushigo.
