Must-Visit Locations and What You’ll Find
Myconid Colony: Your Underdark Hub
The Myconid Colony, located in the Ebonlake Grotto, serves as a relatively safe haven where you’ll meet Sovereign Spaw and various traders. This peaceful mushroom community offers several quests and valuable merchant interactions.
Key NPCs here include Blurg the hobgoblin trader and Omeluum the friendly mind flayer who can help with your tadpole problem. Don’t miss talking to Thulla, a poisoned gnome carrying the coveted Boots of Speed!
Selunite Outpost: Tactical Challenge
The Selunite Outpost features an active defense mechanism that attacks intruders approaching from the front entrance. To safely enter, you’ll need to find the Rocky Crevice on the east side or use creative methods like jumping through the west window.
Inside, destroy the Moonstone with a ranged attack to disable the attacking statues, then flip the lever beside the gate. Your reward? The rare Helmet of Smiting from a gilded chest on the terrace.
Arcane Tower: Puzzle Paradise
The Arcane Tower at the southern part of the map is filled with powerful Arcane Turrets that attack on sight. Instead of fighting your way through, disable their power source located on the tower’s lowest floor. The turrets are vulnerable to electric damage if you prefer combat.
Dread Hollow: Resource Gathering
Head to Dread Hollow to find the Sussur Tree, where you can collect Sussur Tree Bark needed for the Finish the Masterwork Weapon quest. Watch out for Hooked Horrors and the dangerous Bulette boss lurking in this area.
Hidden Treasures Worth Finding
Phalar Aluve Weapon: Located northeast of the Selunite Outpost, this sword is stuck in the ground and requires passing a Religion or Strength check to pull it out.
Shadow of Menzoberranzan: Found behind the Guardian Gate near the Myconid Colony, this rare headgear grants the Shrouded in Shadow ability for invisibility.
Dog Collar: Dig up the tombstone at the southeast part of Dread Hollow to obtain this item, which interacts with a dog bed in the Arcane Tower.

Frequently Asked Questions
Q: Can I return to the Underdark after leaving for the Grymforge?
A: Yes! You can fast travel back to any Underdark waypoint you’ve discovered even after taking the boat to Grymforge. This allows you to complete unfinished quests, collect missed items, or trade with merchants you’ve encountered. The Underdark remains accessible throughout Act 1 and early Act 2.
Q: What level should I be before exploring the Underdark?
A: Most Underdark encounters are balanced for levels 4-5, though some areas like the Arcane Tower and boss fights with the Spectator or Bulette can challenge even level 6 parties. It’s recommended to have at least one party member capable of healing and another who can deal consistent ranged damage before venturing deep into the Underdark’s more dangerous sections.
