There’s a special artifact in Baldur’s Gate 3 that only Gale can unlock in a secret room of Moonrise Towers. The villainous headquarters of the Cult of the Absolute are free for you to explore thanks to the parasite wriggling around in your head, and one of the most notable locations is the first-floor quarters of Balthazar. The castle’s resident Necromancer is off on an important mission for General Thorm, leaving his quarters empty. The area is trapped and filled with secrets. If you explore thoroughly, you can unlock a hidden room with useful information and a powerful new item called the Shadow Lantern. Learn how to unlock the door and how to craft the Shadow Lantern below.

Balthazar’s Quarters are on the First Floor of Moonrise Towers, down the hallway from Z’rell’s desk. Enter the quarters with the key she’ll give you if you do as requested and prove your loyalty to the Absolute.

Inside his chamber, you’ll find a Moonlantern. On the back-left wall, there is a large bookcase with multiple notable books that will be highlighted if you pass a Perception Check. If you press the wrong Protruding Book set a different trap will activate. Only one of these selections will work.

This will unlock the secret room. There’s a lot of useful information here and a powerful new artifact we can unlock with Gale.

Inside the secret room, you’ll find the following unique interactable objects. The first is the Ritual Circle.
