In Baldur’s Gate 3, the spectacular ruins of a mysterious tower in the Underdark hide secrets, but first, you must fix the elevator to unlock the arcane tower basement.
This Guide has been updated for the patch 7 version of Baldur’s Gate 3.
In this guide, you’ll learn step-by-step instructions on overcoming the challenges of fixing the elevator, defeating the guardians, and ultimately unlocking the basement. There are some good items and gear to collect so, prepare yourself for a journey into the depths of the Underdark to uncover the secrets within the arcane tower.
Why Should You Unlock Arcane Tower?
The Arcane Tower is an essential part of the Underdark, with fantastic loot in Act 1. The two most important pieces of gear are the Club of Hill Giant Strength and Staff of Arcane Blessing. With the Club of Hill Giant Strength, you boost your strength to 19, which can be welded in one hand. Therefore, you can combine a shield with it and gain massive strength without feats. The best combination is using a Ranger build and the Titanstring Bow. This will give your rare bow a +4 bonus to attack and do the most damage with a range weapon in Act 1.
The staff of Arcane Blessing is another powerful item because it creates a free use of Bless spell. Moreover, this version of Bless is enhanced via Mystra’s Blessing. You gain an additional 1d4 to saving throws and weapon attack rolls, and an additional 2d4 to spell attack rolls. Not only does this save you on spell slots early in BG3, but the boost in spell attack roll is noticeable and the main reason for clear the content.

Arcane Tower Location
To find the Arcane Tower, venture into the depths of the Underdark (X: -4, Y: -29). This enigmatic structure is located to the southwest of the Underdark beach. Access to the Underdark is accessible through several routes, including the Shattered Sanctum via the Selune Temple. Alternatively, by jumping down through the chasm (X: -543 Y: -366) in the spider cave beneath the blighted village. The easiest way to access the spider cave is by climbing down the well in Blighted Village. Also, ensure you have a potion, spell, or scroll of Feather Fall. In Spider Cave, you must face a challenging battle against the resident spiders. We advise you to reach at least level 4 before going to Underdark and level 5 to explore Arcane Tower.
How to Power the Arcane Tower Generator?
To power the Arcane Tower Generator, use the Sussur Blossom floors on the ground floor to restore the generator. Upon approaching the arcane tower, two turrets will spring to life and target your party. These turrets can be temporarily disabled using lighting damage spells or arrows. You can also use the Sussur Blossom flowers, which emit a soothing luminescence if you found some already. These blue flowers are near the tower’s base and west of the Myconid colony. To deactivate the turrets, pick up a Sussur Blossom flower and throw it next to them.
You’ll discover a broken elevator that can be repaired with Sussur Blossom flower, one located outside the tower behind a tree. Circle the tower jumping on the giant mushrooms, or use the Misty Step spell to reach the lower levels and locate the luminescent tree in the small rocky garden. Collect a Sussur Blossom flower from the tree and enter the tower through the back door, which you can lockpick. Pass the dexterity check, preferably using your character with the sleight of hand proficiency or Astarion. Enter the lowest level of the tower. However, you must complete a few more steps to reach the Arcane Tower basement in Baldur’s Gate 3.
Within the tower’s lowest level, you’ll find the broken elevator and Sussur Blossom flower petals on the floor. Interact with the elevator’s generator, insert the Sussur Blossom flower, and press the combine button. A brief cutscene will play, permanently deactivating all turrets and making the elevator operational again. With the elevator fixed, you can now freely explore the tower and use the elevator to travel between floors.

Defeat the Guardians of the Arcane Tower Bernard
Bernard, the construct, guards the arcane tower alongside other constructs on the tower’s top level. He also holds the key to the Arcane Tower basement. Constructs are difficult opponents, so make sure to save your game before going to the top level to face them. Bernard is resilient to various damage types, making him a formidable opponent. To learn what type of resistance constructs have right click on them and choose the explore option.
If you wish to solve this situation peacefully, locate the Threadbare Book and The Roads to Darkness while exploring the tower, and read them with your character. Next, ascend to the top level and choose the dialogue option “How can I trust…” and quote the book to earn Bernard’s trust. He will place the Guiding Light ring on a table, signaling a peaceful resolution.
If you choose the “There is a light…” option, Bernard and the other constructs will attack you. Engaging in combat with these constructs can be challenging, but there are strategies to overcome them. To target the constructs’ weaknesses, use lightning or cold damage spells, arrows, and abilities. Crowd control spells will also help manage the battle by immobilizing some opponents. Beware of Bernard’s potent melee attacks and his lightning area-of-effect ability. So make sure you remove your range characters from the elevator’s platform as quickly as possible. There are stairs up to the wooden platform that will give your team an advantage on range attacks.
Unlock the Arcane Tower Basement
Once you’ve resolved the situation and obtained the Guiding Light ring, head to the tower’s lowest level using the now-fixed elevator. Place the ring on one of your characters, and a magical button to descend to the Arcane Tower basement will appear. Congratulations, you’ve successfully fixed the elevator and unlocked the Arcane Tower basement in Baldur’s Gate 3. Explore its depths to collect special items and valuable alchemical ingredients that await you.
Prepare yourself for the challenges and mysteries that lie ahead as you navigate the arcane tower’s depths, fix the elevator, defeat the guardians, and unlock the secrets of the basement.
