“Search the Cellar” may sound like one of the most straightforward quests in Baldur’s Gate 3, but it isn’t. This cellar appears to be very plain, and it would be easy for players to think they need to wait for something exciting to happen first. But that’s not the case.

This cellar is like a very small dungeon, complete with puzzles, traps, riddles, and one of Baldur’s Gate 3‘s most intriguing treasures, the Necromancy of Thay. Unless you know exactly what to do, it’s easy to get stuck and give up. Between the lore and the value of the goods, however, it’s best to try and figure out this quest.

Now, players can either destroy the Necromancy of Thay, open it, or give it to certain characters. To destroy it, use any spell that deals radiant damage. Shadowheart can easily do this if the player character doesn’t have access to radiant abilities. Or players can open the book by combining it with the Dark Amethyst.

Getting to the Whispering Depths is not to be confused with getting to the Underdark. Enter the well from the Blighted Village or the opposing door, then search for the Dark Amethyst crystal on the ground by the Spider Matriarch boss. Use the Necromancy of Thay and the option to combine it with the Dark Amethyst will appear. Use it to complete the quest.


Finally, if you have either Gale or Astarion in the party, both will show interest in the book for personal reasons. Giving the Necromancy of Thay to one of them will earn players some approval as well as a conversation regarding the content of the book, back at camp.
