Where to find

• In the Apothecary's Cellar beneath the Blighted Village, behind a locked gate, on an altar.
  • To access the hidden portion of the cellar containing the book, you must move a wardrobe by pulling a lever hidden behind a box, then speak with the magic mirror and either intimidate it or correctly answer its questions:
    • What think you of the Zulkir known as Szass Tam? 'Szass Tam is a foul, wretched creature.'
    • Why might one use balsam ointment? 'To clean a wound.'
    • If you could see anything in me, what would it be? 'I'd look for whatever spell will rid me of this worm in my head.'
  • The locked gate in front of the book can be lockpicked as of release. The Rusted Key found on a shelf in the next room (near the lever that opens a shortcut back to the cellar entrance) can also be used to open the door. Alternatively, spells like Misty Step can be used to bypass the gate.
  • Note that taking the book will trigger a trap. To avoid this, you can enter turn-based mode and place an item of similar weight (like another book) on the pedestal, or simply disarm the two nearby statues.
• To read the book, you must obtain the Dark Amethyst from the Whispering Depths, which can be accessed from the well or the blacksmith's basement in the Blighted Village. The Amethyst is guarded by a Phase Spider Matriarch. X: -550 Y: -350

Notes and Trivia

Act One

• The Necromancy of Thay has three main paths that can be chosen, each with different outcomes.
  • Give to Gale for his condition or to Astarion. Giving it to one of these Companions will net you approval from the one you've given it to, and disapproval from the other. Once a companion has obtained the book, you cannot transfer it to another.
  • Destroy the book. The book can be destroyed only by Radiant damage. Destroying it will net you disapproval from both Astarion and Gale. However it will net you approval from Karlach, Lae'zel, and Wyll if you bring them in your party.
  • Read the book for its dark secrets. Interact with the book and use the option to insert the Dark Amethyst to unlock it. In total, three pages of the book can be turned. Each page you turn prompts a progressively harder Wisdom Saving Throw (DC 10, 15, and 20). The following possible events can occur:
    • Failing one Saving Throw curses you with Whispers of Madness ( Disadvantage on Wisdom Checks for 50 turns).
    • Failing two or more Saving Throws curses you with Baleful Knowledge ( Disadvantage on Wisdom Checks until cleansed by Remove Curse).
      • Some classes receive special options to modify or lower these DCs: Sorcerers may instead make Charisma saves with DCs of 5, 10, and 15. Bards may make Performance checks with the same DCs. All such special options result in the same overall outcomes.
      • Shadowheart is given a special option (as a Cleric of Shar) for turning the third page, lowering the DC to 10.
    • Turning at least one page permanently grants the reader  Speak with Dead. This can be cast as a  Ritual and does not consume a Spell Slot.
    • Turning three pages, regardless of success, grants the Forbidden Knowledge tag and  Forbidden Knowledge passive feature.
    • Closing the book before turning three pages leaves the Search the Cellar quest incomplete and allows the character to reopen the book again later.
• Once the book has been opened by one character, it will not open for any other character. Once all three pages have been turned, the book will refuse to open again for anyone until more knowledge is gained later in the game.
• After reading, the item quote will change from 'It. Is. Not. Too. Late.' to 'Look. Away.'

Act Three

• With the help of Mystic Carrion in Philgraves' Mansion in the Lower City, you can learn - for a 1500 gp fee - that in order to unlock the full potential of the book, you need to seek the The Tharchiate Codex somewhere within Sorcerous Sundries. This step is not necessary, but does help point you in the right direction.
• The Tharchiate Codex is stored in the basement vault of Sorcerous Sundries. You can reach the vault in two different ways:
  • By interacting with the Clasped Book in the bookshelf of Tolna Tome-Monger's office upstairs and going through the portal, or
  • By using the Weave Button labelled 'Vault' on the middle level of Ramazith's Tower.
• Within the vault, the Codex is located in the Elminster section. To unlock the Elminster door, you must first find the lever at the end of the Silverhand section by opening doors in this order: Silverhand, Evocation, Wish.
• After reading The Tharchiate Codex, you can re-read Necromancy of Thay and pass a DC 20 Wisdom saving throw to gain the permanent ability to summon 4 ghouls via the  Danse Macabre spell once per Short Rest. Failing this saving throw has the same effect as before: you're cursed with Baleful Knowledge, but still gain the spell.
  • Reading the Codex also grants you The Tharchiate Codex: Blessing passive feature, which allows you to automatically gain 20 temporary Hit Points after each Long Rest.
• Having the  Forbidden Knowledge feature allows you to safely obtain another permanent bonus from the Mirror of Loss in the House of Grief; see Permanent Bonuses for more details.
