What Is the Arcane Tower in BG3?
The Arcane Tower is a special dungeon in the Underdark . You can find it by going through the Myconid Colony or the SelÃŧnite 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. Youâll find lore-rich items, tough fights, and a haunting atmosphere with mechanical guards and lost knowledge.
How to Reach the Arcane Tower
There are two main paths:
From the SelÃŧnite Outpost : Head west until you find a deep cliff. Use Feather Fall or Misty Step to get down safely.
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.
