Thulla wears Boots of Speed which she stole from Thrinn before escaping Grymforge, presumably by leaping from a balcony near the dormitory at X: -610 Y: 465. The boots are needed to advance Find the Missing Boots. Thulla offers the boots to the party if they successfully cure her of the poison and agree to help her fellow gnomes.
Thulla may also be mercy killed if the interacting party member passes a DC 15 PersuasionCheck to end her suffering. Killing Thulla in this way awards the party with 10 XP, but draws attention from the myconoids, demanding this action be explained.
Alternatively, it is possible to obtain the boots without curing her by stealing them following an Investigation roll or looting her corpse when she dies. Doing so grants the inspiration Swiftly Stolen to party members with the Criminal background.
If Thulla is left to succumb to her poison over the course of the Deliver Nere's Head quest, she can be encountered later as a spore servant wandering around near Spaw. If other deep gnomes are rescued from enslavement and travel to the Myconid colony, they lament her death and transformation.
If Thulla survives Act One, she moves to Angleiron's Cellar with the Ironhand Gnome resistance, where she crafts Runepowder explosives and occasionally discusses resistance plans with the party.
