The Arcane Tower is a Location within the Underdark in Act One of Baldur's Gate 3. The tower overlooks the Ebonlake, and belongs to Lenore De Hurst Lenore De Hurst, however, she has not returned home in over a decade.

Overview[edit | edit source]

Access[edit | edit source]

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 two Arcane Turret Arcane Turrets. It can be reached through the Torchstalk Gulch, recognisable by its dark brown paths paved with deep red mushroom clusters and spots of Torchstalk that cast floating embers into the air.[1]

The area is divided roughly into the entry area, each floor of the tower, and the garden outside the ground floor. Upon initial approach, the doors are shut and the central elevator is disabled, and the floors must be accessed through other means.

The party can use the fungus platforms growing on the southern wall of the tower to Jump Jump their way down to the ground floor. It is a good idea to cast Feather Fall Feather Fall to prevent unnecessary fall damage. Alternatively, using Fly Fly or teleporting (via Misty Step Misty Step) also gets the party down without issues.

Dealing with the Arcane Turrets[edit | edit source]

An active Arcane Cannon.

The Arcane Tower is guarded by automated Arcane Turret Arcane Turrets. They are automatically hostile and shoot at the party members whenever they are in the line of sight and in range; there is a targeting indicator which can show this. Anything that breaks this line of sight, e.g. solid obstacles or Fog Cloud Fog Cloud, effectively stops the attacks.

The turrets shoot and attack in real-time exploration mode as well as in turn-based mode. However, it is recommended to turn on turn-based mode to make movement and controlling the party more manageable.

In general, there are a few approaches to dealing with these the Arcane Cannons:

  • Attacking - the cannons can be directly damaged and rendered inoperable. They have some resistances, and vulnerability to Damage TypesLightning and Damage TypesCold.
  • Override - the cannons can be shut down once restoring power on the generator on the ground floor.
  • Running by / Stealth - this is best done in turn-based mode as it allows the party members to move cover-to-cover between turns.
  • Anti-Magic - as the Arcane Cannons are magical constructs, they can be shut down by placing a Sussur Bloom near them, because of its Sussur Antimagic Field Sussur Antimagic Field.
    • Sussur Blooms can be found in the garden at the bottom of the Arcane Tower, or at the Sussur Tree in Dread Hollow.
    • Attacking a Cannon while it is shut-down by the Anti-Magic field destroys it, as opposed to "knocking it out".
    • Cannons which have previously been rendered inoperable but not destroyed can actually be revived by the Sussur Antimagic Field, by first placing and then taking back a Sussur Bloom near them.

Ground floor (generator room)[edit | edit source]

To restore power to the generator of the Arcane Tower - which activates the elevator and deactivates the automated defences - the party must bring a Sussur Bloom to the power generator. Sussur Blooms can be found at the Garden just outside the door, or on the sussur tree in the Dread Hollow.

The party must interact with the Power Generator to bring up the crafting menu and use it to combine the machine with a Sussur Bloom. The Arcane tower comes to life, granting 25 xp and the inspiration Regeneration Regeneration for party members with the Guild Artisan Guild Artisan background. Once the generator is powered, the Arcane Turrets power down, the Arcane Braziers become lit, and the elevator can be used to ascend and descend between the floors.

First floor (greenhouse)[edit | edit source]

This floor can only be accessed by the restored elevator, by flying, or by using the platforms on the exterior fungus on the south side of the tower. This is a level that contains all the mushrooms required for the quest Help Omeluum Investigate the Parasite Help Omeluum Investigate the Parasite.

The other notable item on this floor is the Threadbare Book containing the phrase: "How can I trust? How should I know? How can I show myself, my darkest me?", which provides an additional option for interacting with Bernard Bernard on the roof.

Second floor (main entrance)[edit | edit source]

The main floor can be accessed directly through the front door of the tower, or via the elevator after it is powered. Opening the Main Door requires succeeding on a DC 15 Sleight of Hand check, or it can be broken down - it has Medium Toughness Medium Toughness and 36 hit points. Alternatively, there is a broken window to the left of the door that can be entered. Opening this door prior to the restoration of power leads to a confrontation with two Arcane Turrets.

A dusty book can be found on this floor. If read it changes its name to Evil's Ascent.

On the northern balcony is the Chest of the Mundane, which is revealed as magical with a successful Arcana check. Taking the clutter from the chest in the inventory, or placing a Sussur Bloom near the chest, dispels the illusion to reveal some scrolls and Mystra's Grace. The latter can provide the party an additional casting of Feather Fall Feather Fall which can help them avoid some damage trying to access the ground floor.

The southern balcony does not contain any notable items, but lets the party access the exterior fungus platforms to the lower levels.

Third floor (bedroom)[edit | edit source]

The Roads to Darkness book on Lenore's desk.

This floor can only be accessed by the restored elevator or by flying. This floor contains documents that the party should inspect prior to ascending to the fourth floor (roof), in order to have a peaceful interaction with Bernard.

The book The Roads to Darkness can be found on the desk at the South-Eastern corner at X: -25 Y: -297 and a Torn-Out Paper on the table close to the elevator at X: -35 Y: -286.

The Orpheus, Prince of the Comet, Part One: Betrayal can be found on top of a bookshelf in the South-Eastern corner X: -31 Y: -296 and be read by Lae'zel Lae'zel to start the quest Discover the History of Prince Orpheus Discover the History of Prince Orpheus. If she is not available, it can be read after picking up The Careful Art of Tir'su Ciphers from the table near the elevator at X: -32 Y: -292 and using it to read the disc (or after succeeding on a DC 20 Intelligence check.

Aside from the books and notes, the magical ring Mage's Friend can also be looted on this floor in a wooden chest by the bed, at X: -29 Y: -273.

Lastly, there is an interactable button at the north-eastern corner of the tower that appears to do nothing when pressed. To make it work, the party must retrieve and equip the Dog Collar from the grave at the Dread Hollow at X: -41 Y: -212, prior to interacting with it. Doing so reveals that the button served as a food dispenser for Lenore's pet, Myrna, as a piece of Raw Steak appears. The party can only do this once.

The fourth floor (roof)[edit | edit source]

This floor can only be accessed by the restored elevator or by flying. Upon arriving at the floor, a dialogue is triggered with Bernard Bernard, who is standing guard by the elevator along with a group of Animated Armours.

Bernard speaks only in poetry, with the scattered lines found throughout the Arcane Tower serving as various command phrases for him. In the first meeting, if the party read The Roads to Darkness they can respond with "Or art though friend, a rescue from my lonely wake?" which prevents Bernard from becoming hostile and attacking. Successfully doing this grants the party 50 XP.

Afterwards, there are several dialogue options / commands the party can use with Bernard, depending on what they have read (see #Bernard's commands).

The Guiding Light ring can be obtained by reciting "How can I trust? How will I ever know? / How can I show myself, my darkest me?" from the Threadbare Book on the first floor, or by destroying Bernard in combat. It cannot be pick-pocketed. Destroying Bernard (or commanding them to drop their weapon) also grants the party the Light of Creation.

There is also a lever next to a bookshelf on this roof, that can be noticed with a DC 18 Perception check. This is an alternate way to open the wall on the first floor that leads to the basement.

Lastly, there is the File:Stool of Hill Giant Strength Unfaded Icon.pngStool of Hill Giant Strength in the northeastern corner, behind the Animated Armour, that party members can sit on and notice its magical effect. If they break the stool and pass the subsequent perception check, they can obtain the Club of Hill Giant Strength from its debris.

The basement (secret room)[edit | edit source]

Flying down to the secret basement room.

There are several ways to access the basement:

  • Using the elevator with Guiding Light equipped (an additional "Basement" button appears at the controls)
  • Using Fly Fly or Misty Step Misty Step to go through a gap from the first floor
  • Using Mage Hand Mage Hand or a ranged attack to activate a lever under the staircase to open the wall
  • Activating the lever on the fourth floor hidden next to a bookshelf.

In the basement, aside from more Tongue of Madness and Timmask Spores, the party can also find the Staff of Arcane Blessing leaning against a table, The Sparkswall in a gilded chest, and an assortment of scrolls in the chest and various rows of books.

Torchstalk Gulch[edit | edit source]

To the east of the tower, this unnamed area of the Underdark has deep red mushroom clusters and spots of Torchstalk that cast floating embers into the air. The corpse of an unfortunate Drow can be found, having been killed by an unexpected fall.

The party can climb mushrooms along the wall to reach an upper level.
