Quick Answer
In the Tower of Knowledge, throw daggers at The Necronomicon, slash when it falls, and retreat during goat form. Bring the Azure Torch to ignite the book; afterward, your acid vial opens blocked routes through the tower.
How do you beat The Necronomicon?
You can fight from range, then close in for slashes when the book falls.
Throw from a distance
Keep your distance and throw daggers, piercing daggers, or occult knives at the book. The Necronomicon repeatedly applies status effects from range, so expect pressure even while you stay back.
Slash the fallen book
When the book falls, move in and slash it during that opening. Use your Azure Torch to set it on fire as well.
Wait out goat form
When The Necronomicon takes goat form, pull away and keep your distance until it changes back. Then return to ranged throws and attack the book when it falls again.
Where is The Necronomicon?
You reach The Necronomicon through the locked doors near the Storm Gem in the Tower of Knowledge.
Rotate the stairway
From beneath the Storm Gem location, air dash across to the switch. Activate it to rotate the stairway, then head up the stairs.
Get the Forbidden Archives Key
Take the elevator down to Bodine, also called Boudin, and receive the Forbidden Archives Key. It unlocks the doors near the Storm Gem.
Reach the boss
Go through the unlocked doors, where you find another safe point. Take the elevator up and pass the enemy gauntlet before the boss fight.

What weapons should you bring, and what is its weakness?
Bring throwing weapons and the Azure Torch; you can ignite the book, but its elemental weakness is currently unknown.
| Weapon | Use in this fight |
|---|---|
| Daggers | Throw from a distance while the book stays out of melee reach. |
| Piercing daggers | Use for the same ranged approach. |
| Occult knives | Throw at the book; you find these after dropping through the tower's trapdoor. |
| Azure Torch | Set the book on fire. |
Check the throwing weapons guide for your ranged options.
Burning the book works, but that alone does not tell you its elemental weakness or resistance values. Those details remain unknown; more details will be added as they become available.
What does The Necronomicon drop, and where do you go next?
You receive an acid vial, which coats basic throwing daggers with acid. You can then break the tower's face pimples.
Use those acid-coated daggers on the face pimples throughout the Tower of Knowledge. Breaking them reveals secrets and weapons.
For progression, return to the obstacle near Boudin / Bodine, who is now dead. Break the face pimple there to open a path toward the mausoleum.
That route also lets you open the door near the now-dead campfire companions from the beginning.
The complete drop list remains unknown; more details will be added as they become available. For other encounters, use the Queen's Domain bosses guide.
