Are you ready to embark on a spellbinding adventure through the Arcane Tower in Baldur’s Gate 3? This comprehensive walkthrough will lead you through this optional location, teeming with side content, nestled in the enigmatic depths of the Underdark.

Locating the Arcane Tower

You can find the Arcane Tower tucked away in the southwestern reaches of the sprawling Underdark. Begin your journey from the tower’s front gate and venture onto the left-side balcony. Here, you’ll notice some peculiar mushrooms adorning the tower’s exterior. Utilize the “Grant Flight” spell to gracefully leap from the balcony and float onto the vibrant blue mushrooms. Continue to employ the spell until you reach the lowest level of the tower.

Level 1

Upon reaching the tower’s base, make your way to the luminous trees. Here, you’ll discover a Sussur Bloom. Procure it and advance towards the tower’s rear door. Interact with the door; you can pick the lock, cast a knock spell, or deliver a series of precise blows with a melee weapon to gain access. Enter the Arcane Tower, equipped with the Sussur Bloom, and thus begin your journey on Level 1.

Place the Sussur Bloom onto the generator, nestled in the room’s centre. Click on the generator to open the combined item screen, then simply drag the Sussur Bloom into the empty slot. This action activates the generator while simultaneously deactivating the Arcane turrets.

Level 2

After successfully activating the elevator, ascend the stairs and step into the elevator. Press the button once to reach Level 3.

Level 3

On Level 3, you’ll encounter a Threadbare Book just outside the elevator. Additionally, collect a Tongue of Madness near a brown mushroom and Timmask Spores from a wooden shelf.

Level 4

Return to the elevator and make your way up to the fourth floor. Here, interact with a lever to allow your team to join you. Be sure to read the Dusty Book situated on a table. On the balcony of Level 4, you’ll find a chest containing an item that will become instrumental after passing the Arcane test.

Level 5

Return to the elevator and ascend to Level 5. Read the Torn-Out Paper, placed on a table near the elevator, and delve into the book “Roads to Darkness.”

Level 6

Your final ascent takes you to the sixth and topmost floor. Here, you’ll meet Bernard, an electrified automaton. Bernard will present you with a couplet challenge, and the solution lies in the three books you’ve read earlier.

Select the following lines:

“Or art thou friend, a rescue from my lonely wake?”

“How can I trust? How will I ever know? How can I show myself, my darkest me?”

Choosing this option leads Bernard to place the Guiding Light directly onto the table beside him. Equip this ring on your finger, revealing a secret button on the elevator that grants access to the basement.


Descend to the basement, where you’ll discover extra loot in boxes and bookcases. Among the treasures, find the Staff of Arcane Blessing and Sparkswall inside a Gilded Chest.

A Heartfelt Farewell

Before departing from the Arcane Tower, read the notes from the pile of books near Bernard to receive a random item. And for a touching conclusion, return to the tower’s top floor, where Bernard awaits. Select the dialogue, “The silence stretches on – I’m all alone. Please, can I hold your hands, for just a while?” for a heartwarming hug from Bernard.
