The «Annals of Karsus» in Baldur's Gate 3 is a forbidden book that you need to acquire during the personal quest «The Wizard of Waterdeep». Gale believes that from this rare document, the team can learn important information about the Netherese crown on the Elder Brain. Unfortunately, it is hidden in a magical vault, and to reach it, you need to solve a puzzle. We made this guide so that completing this quest would not cause you any difficulties.
The book «Annals of Karsus» is located in the Sorcerous Sundries cellar «Sorcerous Sundries» — a shop in Baldur's Gate. You can get here through a portal in the shop itself. First, you need to go up the stairs and hack the left metal door. Next, interact with the clasped book on the shelf to your right. It will open a portal that leads players to the vault.
We recommend using a character with a high «Perception» score, as the rooms in the cellar are full of traps. To get to the next room, you will have to open the oak door in front of you, and upon entering, hack another door.
In the third room, players will face three magical doors that teleport them to other places. Here are the doors you need to enter to obtain the «Annals of Karsus»:
«Silver» should be behind your character, and in the room beyond it, there is a lever that you need to pull. After that, you must return to the previous room and go through the door «Demon».
Karsus's vault door will shine, and you simply need to go to the next room to get the «Annals of Karsus». In this room, you will also find the «Dispel» scroll, which we definitely recommend your wizard to study.
To open Elminster's Vault, you need to follow roughly the same principle as before. The order of opening the doors is as follows:
«Wish», like previously «Silver», should be behind your character. There, you need to pull the lever and then enter absolutely any door. This way, you will find yourself in Elminster's vault, where you can find and read the continuation of the infamous «Thayan Necromancy».
