Underdark

The caverns of the Underdark.

The Underdark is a region in Act One of Baldur's Gate 3. It is a vast series of caverns and tunnels devoid of sunlight but full of dangerous creatures and even more dangerous mushrooms, but also contains a multitude of alchemical ingredients that are hard to find elsewhere.

Overview

The Underdark in Baldur's Gate 3 is only a small portion of the true Underdark. The Drow, Duergar and Deep Gnomes are native to the Underdark.

The following locations contain known access points into the Underdark:

• Ladder from the Defiled Temple, arriving in the Selunite Outpost.
• Elevator from the Zhentarim Hideout, arriving in the Storehouse.
• Mushroom Circle in the Overgrown Tunnel to a corresponding circle in Torchstalk Gulch
• Falling into the hole in the Whispering Depths, arriving in the Minotaur Hills.  Feather Fall or the ability to  Fly must be used or a cutscene will show the party falling to death.

Areas

Map of the Underdark, with the Storehouse and Minotaur Hills highlighted.

Storehouse

Main article: Storehouse.

The Storehouse is in the most north-eastern quadrant of the Underdark map. This area is recognisable for its aging pale wooden interior and is free of any enemies.

Enter the Underdark through this area when departing from the over-world's Zhentarim Basement.

Minotaur Hills

Considered part of the Storehouse, this unnamed area of the Underdark is recognisable thanks to its bright green grass and whimsical red mushrooms with swirling paths featuring wandering Minotaurs. This area is directly to the south of the Storehouse via the rope netting.

Map of the Underdark, with Ebonlake Grotto, Myconid Minefield, and Giant Bird Nest highlighted.

Ebonlake Grotto

Main article: Ebonlake Grotto.

The Ebonlake Grotto is recognisable for its densely packed oversized mushrooms, and roaming Myconids amidst which reside several NPCs and merchants.

Myconid Minefield

Considered part of the Ebonlake Grotto and in its south-east part, this nameless area of the Underdark is recognisable for being full of dangerous mushrooms such as Timmask and Bibberbang, which are a particularly dangerous combination with Torchstalk mushrooms that can quickly turn the area into a series of explosions.

Giant Bird Nest

Considered part of the Ebonlake Grotto and to its south-west, this unnamed area is an unremarkable corridor connecting Ebonlake Grotto, the Dread Hollow and the Decrepit Village. It is most recognisable for the giant bird's nest.

Dread Hollow

Main article: Dread Hollow.

The Dread Hollow is in the north-west of the Underdark. This area is recognisable for the large and brightly shining Sussur Tree, as well as the roaming Hook Horrors and a hostile wizard, Filro the Forgotten, living along its branched roots. A Bulette can also be spotted in the area.

To the south lies the tombstone of Myrna, a pet dog of Lenore.

Bibberbang Grotto

North-east of the Sussur Tree in the Dread Hollow section of the Underdark, the Bibberbang Grotto is an unnamed area of explosive and densely growing Bibberbang mushrooms, trapping Baelen Bonecloak.

Arcane Tower

Main article: Arcane Tower.

The Arcane Tower is in the south-west corner of the Underdark map. This area is recognizable by its neatly built stone entryway that opens to a front garden featuring Arcane Cannons.

Torchstalk Gulch

Considered to be part of the Arcane Tower and to its east, this unnamed area of the Underdark is recognisable by its dark brown paths paved with deep red mushroom clusters and spots of Torchstalk that cast floating embers into the air. The corpse of a Dead Drow can be found, having been killed by an unexpected fall. It can be spoken to with  Speak with Dead.

Also, a few mushroom circles can be found here, one of which X: 98 Y: -283 leads to the Sunlit Wetlands X: -74 Y: 210.

Festering Cove

Main article: The Festering Cove.

The Festering Cove is a partially hidden location containing some Kuo-toa worshipping their god BOOOAL. It can be reached by climbing down the cragged rock in Torchstalk Gulch X: 80 Y: -241.

Map of the Underdark, with the Selûnite Outpost and Battlefields highlighted.

Selûnite Outpost

Main article: Selûnite Outpost.

The Selûnite Outpost is in the south-east corner of the Underdark map. This area is recognisable by its crumbling stone walls, grated windows, and tattered blue banners to the goddess Selûne. A statue of the goddess holds up a bright moonstone, which channels energy into the front gate's defences.

The Outpost can be reached from the Shattered Sanctum.

Ancient Battlefield

Directly north of the Selûnite Outpost, this unnamed area of the Underdark is recognisable by its field of scattered wooden barricades and long-dead skeletons of ancient fighters.

Petrified Battlefield

To the west of the Selûnite Outpost, this nameless area of the Underdark is recognisable by its purple Glowing Gems and several petrified Drow as well as one Spectator.

Decrepit Village

Main article: Decrepit Village.

The Decrepit Village is the central area of the Underdark and fairly vertical. It is recognisable for its ramshackle wooden structures and rope netting enclosures. The lowest level of the Decrepit Village features a sandy beach strewn with the bodies of dead Deep Gnomes and Duergar. A boat rests at one dock, ready to take the party to Grymforge based on the story path of their choosing.

Grymforge

Main article: Grymforge.

Grymforge is an expansive and abandoned settlement on a separate map, containing the Adamantine Forge. It is accessible via the boat at the Decrepit Village.
