Retrieve Omeluum is a side quest in BG3 that takes place during Act 3 of the game. Unlike the rest of the mind flayers in the game, there is actually a friendly one named Omeluum. We first encounter him in the Myconid colony to help him with his investigation of the Illithid parasite. However, he disappears once he brews you a potion but ultimately fails to heal you.
In this guide, we will investigate the mysterious disappearance of the only friendly Mind Flayer and try to bring him back to his friends. Retrieve Omeluum quest can bug or simply fail by a lot of things. We recommend that you don’t steal Githyanki’s egg and hand it over to Esther. Blowing up Steelwatch foundry also fails this quest prematurely.
How to start the Retrieve Omeluum quest
To start the Retrieve Omeluum quest in BG3, you first need to travel to the Society of Brilliance Lodge. This lodge is famous for giving sanctuary to creatures from the Underdark. Find and talk to Blurg inside the Society of Brilliance Lodge. He will tell you that his friend Omeluum has been missing for some time now. Talking to Blurg will automatically start the quest.
You can also start this quest by going to Iron Throne prison to save Wyll’s father, Grand Duke Ravenguard. Once there, you can find Omeluum in a cell, and it will trigger the quest. However, there is a chance that Omeluum will not be present in Iron Throne prison if you don’t talk to Blurg first.
How to complete the Retrieve Omeluum quest in Baldur’s Gate 3
Lord Gartash’s people captured Omeluum, and he is now kept in Iron Throne prison so they can experiment on him. The only way to reach this area is by finding a ship that can take you underwater. To find a submersible, you first need to travel to Grey Harbour Docks (X: -172, Y: -148), which are located to the South of Baldur’s Gate waypoint and Southwest of Lower City central wall.
Use lockpick or spells to unlock the steel doors and enter Flymm’s Cargo. Go to the left corner at (X: -165, Y: -142) to find some wooden blocks. Remove these blocks to discover a closed hatch leading to the Flymm’s Cargo basement. Keep going straight and turn left to reach the docks. Either talk to the submersible owner there or use the invisibility spell to enter the submersible undetected. This makes you one step closer to retrieving Omeluum in BG3.
Once inside the submersible, Lord Gortash will give you a warning about blowing up Iron Throne prison with you in it. Ignore his warning and dock at the Iron Throne. You will hear Omeluum’s voice inside your head. Select the following dialogue option.
- “Where are you?”
This will mark his location on your map. You have very limited time and only 6 turns to retrieve all the prisoners. We recommend saving Grand Duke Ravenguard and Omeluum as the highest priority. Disband your party and send them to find Grand Duke while you go to find Omeluum.
Make sure to use Misty Jump and Haste spells a lot. Bring minions if you have any, or use the Greater Invisibility spell to avoid any encounters. Omeluum’s cell is to the Southwest of your starting point. He is restrained, and you need to free him first (X: -38, Y:19). Luckily, he has a spell that can instantly send you back to the submarine, saving precious moves.
Ignore any dead companions for now, as you can always revive them later with the help of Withers. Just make sure all the prisoners are inside the submarine, and you are, too. If you survive this gauntlet, everything will be fine. Take the prisoners back to the surface, and it will complete the Retrieve Omeluum quest in BG3. It will also allow you to progress Wyll’s companion quest, The Blade of Frontiers.
