Dark Amethyst is a key item in Baldur’s Gate 3 that you can obtain from the Whispering Depths dungeon to open the Necromancy of Thay book. This item is well hidden and is protected by one of the scariest bosses during Act 1 of the game.
In this guide, we will teach you how you can enter the Whispering Depths and easily collect Dark Amethyst.
Baldur’s Gate 3: Dark Amethyst location
Dark Amethyst is present in the Whispering Depths dungeon, which is beneath the Blighted Village. Travel west from the Druid Grove or east from the Goblin Camp to reach the Blighted village in Baldur’s Gate 3.
Once you safely enter the village from its main entrance, locate the well at (X: 24, Y: 400). Pass the perception check to open the entrance of the well. Jump down, and you will land inside the Whispering Depths dungeon.
This area is full of webs and phase spiders. Dark Amethyst is present (X: -561, Y: -357) near their nest where the Phase Spider Matriarch is. You can ungroup a party member and cast the Invisibility spell on them to avoid detection. This way, you can easily steal the Dark Amethyst without triggering a fight.
In case you start the fight, make sure to burn the web bridges and Phase Spider Matriarch eggs first. Kill her children before going all crazy on her. She drops important loot, including the Poisoner’s Robe.
How to Use Dark Amethyst in Baldur’s Gate 3?
Dark Amethyst has two purposes in Baldur’s Gate 3. To open necromancy of Thay book and complete the Search the Cellar side quest.
When you are inside the Blighted Village, go to the Necromancer’s House and find the hatch to the basement (X: -33, Y: 377). Inside the basement, remove the boxes and pull a lever (X: -702, Y: -355) to find Dark Journal. Reading it will start the quest automatically.
Defeat the Ornate Mirror at their own game and go further down the cellar to reach the laboratory. Take the Rusted Key and use it to open a locked door. This secret chamber contains the Necromancy of Thay book.
Once you have the book, combine it with Dark Amethyst to open it. You will need to pass three increasingly difficult Wisdom Checks (DC 5,10,15) as you turn over the pages. Once you open and read the book, the Find the Cellar quest concludes.
