Baldur’s Gate 3 is filled with hidden secrets, rewarding exploration, and challenging puzzles. One of the most intriguing early-game mysteries is the Dark Amethyst, a rare gem tied to the powerful Necromancy of Thay book. If you’re wondering where to find this elusive item and how to use it, this guide will walk you through every step—while also helping you prepare for the dangers ahead.

Where to Find the Dark Amethyst in Baldur’s Gate 3


Your journey to obtain the Dark Amethyst begins in the Blighted Village, a goblin-infested ruin in Act 1. Near the village’s central waypoint, you’ll spot an old well—this is your entry point.

Preparing for the Challenge


Before descending, ensure your party is well-rested and equipped for combat. Inside, you’ll face:
  • Phase Spiders (Level 3) – These enemies teleport and use poison attacks.
  • Ettercaps (Level 3) – Melee fighters that can ensnare your party.
  • Phase Spider Matriarch (Level 5) – A deadly mini-boss with area control abilities.

Navigating the Spider Lair


Once inside the well, head to the northwestern corner of the cavern. You’ll battle spiders and ettercaps before reaching a large chamber where the Phase Spider Matriarch lurks.
Combat Tips:
  • Destroy web bridges to isolate enemies.
  • Avoid egg clusters—they hatch into swarms of weak spiders.
  • Use ranged attacks since the Matriarch teleports frequently.

After defeating the enemies, descend to the lower section of the cavern. There, glowing purple on the ground, you’ll find the Dark Amethyst.

What is the Dark Amethyst Used For?


The Dark Amethyst is the key to unlocking the Necromancy of Thay, a forbidden book with dark powers. Here’s how to access it:

Locating the Necromancy of Thay


  • Return to the Blighted Village and enter the building behind the waypoint.
  • Look for a hatch near the counter—this leads underground.
  • Inside the cellar, move or destroy the top crate on the back wall to reveal a hidden lever.
  • Pull the lever to shift the bookshelf, exposing a secret passage.
  • Bypassing the Mirror and Traps


  • Speak to the Ornate Mirror—pass a skill check (Deception or Intimidation) to proceed.
  • In the next room, grab the Rusted Key from a shelf on the far right.
  • Disarm the floor trap near the Rusted Iron Gate before proceeding.
  • Disarm the Gargoyle trap as you enter the final chamber.
  • Unlocking the Necromancy of Thay


  • Use the Rusted Key to open the gate.
  • Place the Dark Amethyst into the book to begin reading.

  • Warning: Reading the Necromancy of Thay requires multiple skill checks. If you fail, your character may suffer negative effects. Save Inspiration Points to improve your chances!

    Why the Dark Amethyst is Worth the Effort


    Unlocking the Necromancy of Thay grants powerful abilities, including:


    • Necrotic resistance
    • Summoning undead allies
    • Enhanced dark magic spells


    For players pursuing a dark or necromancer playthrough, this book is a game-changer.

    Final Tips for Success


    • Bring a Rogue to disarm traps efficiently.
    • Use Fire or Lightning spells—spiders are weak to these elements.
    • Save before attempting skill checks to avoid permanent penalties.


    By following this guide, you’ll secure the Dark Amethyst, unlock the Necromancy of Thay, and gain a significant edge in your Baldur’s Gate 3 adventure. Happy looting!
