Navigating the subterranean dangers of the Underdark in Baldur's Gate 3 leads players to unique allies, including a peaceful mind flayer named Omeluum. Finding a cure for the illithid tadpole remains a central goal during Act One, making Omeluum's proposal particularly compelling. This quest walkthrough explains how to initiate the research, gather essential ingredients, and navigate the consequences of the experiment.
Starting the Quest in the Myconid Colony
To begin this quest, travel to Ebonlake Grotto in the Underdark and locate the hobgoblin scholar named Blurg. Conversing with Blurg about your parasite infection prompts him to call upon his associate, Omeluum, to inspect your mind. Omeluum offers to brew an experimental potion to weaken the parasite, but requires two rare components from the region.
Locating the Required Botanical Ingredients
Omeluum requests a fresh Tongue of Madness and a cluster of Timmask Spores to prepare the elixir. Both items can be harvested inside the Arcane Tower, which is situated in the southwestern region of the Underdark. Players must carefully bypass the defensive arcane turrets and reach the tower garden to collect these fungi.
Brewing and Drinking the Experimental Potion
Once you have gathered the required materials, return to Ebonlake Grotto and deliver them directly to Omeluum. The mind flayer immediately crafts the mixture and instructs your character to drink it entirely. Consuming the potion triggers consecutive saving throws as the parasite resists the sudden influx of magical alchemy.
Quest Outcomes and Claiming Your Rewards
Despite Omeluum's best efforts, the potion fails to remove the tadpole and instead amplifies its underlying strength. To apologize for the dangerous side effect, Omeluum offers to sell or trade a rare Ring of Mind-Shielding. Acquiring this ring provides useful defensive benefits, completing this memorable Underdark encounter.
