On this page of the guide to Baldurs Gate 3, you will find a walkthrough for the Search the Cellar quest. This solution will help you complete the quest successfully.
- Find the Ancient Tome
- Unlock the Ancient Tome (optional);
- Destroy the Ancient Tome (optional);
In an abandoned village, right next to the fast travel point (M5:4) there is a cottage. Inside, you can find a hatch leading to the cellar. Enter it - you'll see a cave full of chests. There is an undead in each of them. If you interact with them, you will be attacked.
On the opposite side of the room you will find a mirror to which you can talk. At some point, it will ask you about the lich. In order for complete the check, you must confirm that you are its servant, and then choose the following answers:
- "A dead lich. I wish he'd done it 100 times.";
- "Cleansing wounds";
- "I would like to know the spell that will free me from the parasite in my head.";
If you give the wrong answer, you will be attacked.
There is a workshop behind the mirror. You'll find a tome on the table in front of the entrance. It describes the performed experiments.
Take a look at the fire trap located behind the bars. The Book of Necromancy is behind it. Destroy the door or open it with the thief's tools. Go inside (it is good to drink a fire resistance potion before that) and take the book. It turns out that to open it you need a key. At this point, you can do two things.
Destroy the book
The first option is to destroy the book. This variant is very easy. It requires you to cast a light damage spell (e.g. Shadowheart's Guiding Bolt) on the book.
Find the key
In order to open the book, you must go to the Whispering Depth. There are a few available paths - they all start in the Blighted Village.
- the well (M5;7) next to a fast travel point.
- a hole in the rock in the basement of the building opposite the apothecary house.
In the caves you will find a group of Phase Spiders. These are some of the more difficult opponents in the game. They are able to teleport and can inflict great damage. In addition, they are led by a Phase Spider Matriarch, a powerful opponent. You'll find Dark Amethyst (item needed to open the book) in her vicinity. You can try to sneak past her or engage in a fight (instructions on how to defeat her can be found on a separate page of the guide).
After you have found the key, you can activate the book from the inventory level. You must also decide whether you want to keep the book for yourself and learn Speak with Dead or give it to Gale or Astarion.
