Help Omeluum Investigate The Parasite BG3 Quest Guide

Exploring the Underdark in Baldur's Gate 3 introduces adventurers to many unusual allies, including a friendly Mind Flayer named Omeluum. Seeking to understand the strange mind flayer parasite inside your head, Omeluum offers to research it in exchange for specific alchemy ingredients. Completing this quest provides key insights into your condition and unlocks useful rewards for your journey.

Finding Omeluum in the Underdark

To begin this quest, travel to the Ebonlake Grotto within the Myconid Colony located in the Underdark region. Inside the colony, speak with the hobgoblin trader Blurg, who will introduce you to his associate Omeluum. Once you explain your unique tadpole situation, Omeluum agrees to conduct an investigation if you bring him rare ingredients.

Gathering the Required Ingredients

Omeluum requires two specific items to prepare his investigative potion: Tongue of Madness and Timmask Spores. Both of these ingredients can be harvested within the dangerous Arcane Tower situated in the southwestern part of the Underdark. Carefully bypass the tower's defenses to explore the garden area and collect the necessary components.

Drinking Omeluum's Potion

Return to the Myconid Colony and hand the collected ingredients over to Omeluum so he can brew the elixir. Drink the potion when prompted and prepare to undergo a series of challenging saving throws. Successfully navigating or failing these checks will alter the narrative slightly, but the parasite ultimately resists extraction.

Quest Rewards and Final Outcomes

Although the potion fails to remove the parasite, Omeluum offers compensation for your assistance in his research. He will offer you the Ring of Mind Shielding, an item that grants advantage against being charmed. Completing this storyline provides valuable lore and essential options for managing your Illithid powers.
