If you’ve explored the mysterious Underdark in Baldur’s Gate 3, you’ve probably seen the Arcane Tower . It's a tall, magical building packed with loot, lore, puzzles, and danger. This guide will show you how to enter the Arcane Tower , turn off its traps, solve its secrets, and collect all the best rewards. Whether you want powerful gear or background story, this walkthrough covers everything you need in 2025.

The Arcane Tower is a special dungeon in the Underdark . You can find it by going through the Myconid Colony or the Selûnite Outpost. The tower was once controlled by a powerful wizard named Lenore De Hurst , who filled it with traps, turrets, and magical puzzles.

If you enjoy exploration and clever puzzles, this is a must-visit spot. You’ll find lore-rich items, tough fights, and a haunting atmosphere with mechanical guards and lost knowledge.

There are two main paths:

1. From the Selûnite Outpost : Head west until you find a deep cliff. Use Feather Fall or Misty Step to get down safely.

2. From the Myconid Colony : Go south through the Bibberbang field. Keep walking until you reach the tower base.

Be careful. Arcane Turrets guard the entrance and will attack on sight. Bring ranged damage or stealth options.

Disable the Arcane Turrets

To stop the turrets:

1. Find the power source near the elevator.

2. Place Sussur Bark into the power generator. You can get it from the Sussur Tree nearby.

3. Once powered, the turrets shut down automatically.

You’ll also get access to the elevator and new floors.

BG3 Arcane Tower Elevator Activation

With power restored, the elevator comes online. Look for the glowing button at the base. If it doesn’t work, make sure the Sussur Bloom is placed correctly and glowing. This lets you move freely through the tower’s many floors.

First Floor – Entry Level

Loot books and scrolls. Check for:

• Scroll of Mage Armor

• Alchemist’s Fire

• Letter to Lenore

• Threadbare Book

• Dog Collar (near the elevator panel)

Second Floor – Study Room

Here you’ll find:

• Animated Armor that attacks

• Bookshelves with magical notes

• Dusty Book and Roads to Darkness

• Chest with Staff of Arcane Blessing and Fireball scroll

Third Floor – Plant Room

This floor has magical plants. Some can explode. Hidden behind a shelf is a note about Lenore’s paranoia. Look for the Chest of the Mundane —it hides strong items as basic ones. Also check for:

In this room:

Unlock every bookshelf, open every crate, and don't forget:

• Threadbare Book , Dusty Book , and Roads to Darkness are used in Bernard’s puzzle.

• The Art of Tir’su Ciphers help you decode ancient lore.

Jump carefully between balconies using Feather Fall or Misty Step to avoid fall damage .

To do well in the tower:

• Bring a Rogue (for traps and locks)

• Bring a Wizard/Sorcerer (for arcane checks)

• Bring a strong melee like Lae’zel or Karlach

You’ll face magic, puzzles, and mechanical foes. Variety helps.

• Use Detect Magic to find hidden objects

• Read every book you pick up—some hold clues

• Use Feather Fall to leap between balconies

• Save often before trying a new interaction
