Gale wants to know more about the Crown of Karsus in Baldur’s Gate 3, and if you want to help him learn everything there is to know about the artifact on the Elder Brain, you need to unlock the Sorcerous Sundries Vault. Reaching the vault will take plenty of stealth to achieve without causing issues, but it’s certainly possible, and I’m here to help.
Where to Find the Sorcerous Vault in BG3
To find the Sorcerous Vault, you need to unlock Tonla Tome-Monger’s office on the second floor of Sorcerous Sundries. Inside the office, there is a bookshelf with a hidden lever on a loose book. Before going to the vault though, I would recommend speaking to the librarian before going to her office. With enough persuasion, you can get Tolna to give you hints about the vault’s location.
After speaking to Tolna, head to the stairs behind you and go to the path on the left. You will find Tolna Tome-Monger’s office. It’s easy to lockpick this door, and Astarion was able to get past it in one roll for my own party, but you need to watch out for the sentries.

I recommend going invisible with one of your characters. Make sure they are separated from the rest of the party and pick the lock while you are invisible. Once you are inside the office, it’s time to unlock the Sorcerous Sundries Vault.
How to Open the Sorcerous Vault in BG3
The Sorcerous Vault is unlocked by pulling the clasped book on the bookshelf in Tolna Tome-Monger’s office. You can find this book on the first bookshelf to the right when you enter the room, and pulling it will cause a portal to appear. This blue portal will form on the far left side of the room, but I still recommend looting before you jump in. There are some additional snippets or lore only found in Sorcerous Sundries.
Some of the books will detail how the hidden vault works, and you can even loot a chest key from the same bookshelf. Take all you can and then jump into the portal. You’ll be thrown into a room full of traps, so all the knowledge you can get is important.
