How to get the Necromancy of Thay and, more importantly, how to open the Necromancy of Thay to unlock its dark powers in Baldur’s Gate 3. Many players find the book but get stuck trying to find the key; this guide covers the exact Necromancy of Thay location and the step-by-step process to complete the "Search the Cellar" quest in Act 1.
We start in the Blighted Village to find the hidden Apothecary’s Cellar. I’ll walk you through the Ornate Mirror answers and the traps protecting the tome. Next, we head into the Whispering Depths to show you how to find the Dark Amethyst (the essential keygem) near the Phase Spider Matriarch’s nest.
Whether you want to unlock the Necromancy of Thay for the "Speak with Dead" spell or you're looking for the permanent "Forbidden Knowledge" buff, this BG3 (Baldur’s Gate 3) walkthrough has you covered. In Act 3 The Tharchiate Codex is needed to fully master the book to summon your own army of ghouls!

- How to get the Dark Amethyst: The exact location in the Whispering Depths.
- How to open the Necromancy of Thay: How to insert the gem and start the reading process.
