One of the side quests in BG3 is to Investigate the Beach, which becomes available halfway through Act 1. The quest’s goal is to protect Mirkon, a Tiefling Child, from the enemies in the Druid Groove and talk to another one, Mol.
As simple as it sounds, Investigate the Beach quest in BG3 is very challenging, and you might struggle a lot if you have no idea how to complete it. Follow our guide and help yourselves to complete this quest.
How to start the Investigate the Beach quest in BG3
Unlike most BG3 quests you acquire from NPCs, Investigate the Beach will be given to you automatically. Getting the “Investigate the Beach” quest is very simple. You must travel to the Secluded Cove beach in Druid’s Grove, northeast of Mainland Wilderness.
The exact location of this area is to the East of Druid Grove. Follow the path in the image to reach the beach. The quest will automatically start once you reach the destination.
Investigate the Beach quest walkthrough
Once you reach the beach region on Secluded Cove, you will hear a beautiful, melodious song. This is a Siren’s song, and the next thing you want to do is to locate its source. Head towards the Eastern side of the beach to locate the source of the music.
From the Eastern side, head further down towards the cliffs to find a Tiefling child, Mirkon, at the coordinates (X: 332, Y: 547). Upon talking to Mirkon, you will realize he is tranced by the music and was lured here by it.
You need to attempt to Investigate the Beach quest in BG3 before resolving the conflict inside the Druid Grove. Otherwise, Mirkon will be dead if you reach the shore at the Secluded Cove and can’t progress the quest. This is a bug and hasn’t been fixed until the latest patch.
Defeat harpies to save Mirkon
Mirkon will try to get closer to the musical source, and at the same time, four harpies will appear in the scene. It turns out that one of the four Harpies was singing that song to lure Mirkon towards them. This is your clue to fight the Harpies and save Mirkon from his imminent death.
The troubling part of this fight is that Mirkon will still listen to the song of the harpies and keep trying to get closer to them in BG3. To prevent Mirkon from being hunted by the harpies, target the singing Harpie and get rid of it as a priority.
The best way to defeat harpies early is to position your party on the high ground by taking advantage of the cliffs. As you might know, High Ground in Baldur’s Gate 3 can be quite beneficial. One of your members should stay close to Mirkon at all times to save him. Use ranged weapons to fight harpies because they can fly, as the melee attacks will be ineffective.
Locate Doni and talk to Mol
After you clear the Harpies from the scene, speak to Mirkon. He will thank you for saving him and refer you to an NPC named Doni. Mirkon will tell you to inquire about Dragon’s Lair from Doni.
Luckily, finding Doni is not tricky. Just head along the road towards the western side of the Beach. You will find him near a crossroad at The Hollow. Upon speaking to Doni, he will open a hatch to a Lair for you. Get inside the Dragon Lair (Tiefling Hideout) and find Mol to talk to her. She is standing under an archway near the entrance.
After the conversation with Mol, she will ask for your help. This will end the quest: Investigate the Beach in BG3.
