Wondrous Item

Varies Requires attunement by a cleric, sorcerer, warlock or wizard Requires Attunement

The Dark Arcananomicon is a comprehensive volume detailing ancient and terrible funerary rites as well as horrifically specific information pertaining to different realms. The book also has information about ancient rituals, necromancy and dark arts. The Dark Arcananomicon itself is a thick black leathered book with a golden spine and purple binders. The symbol on the book is the skull of a dragon with purple outlines.

A creature attuned to The dark arcananomicon must spend 200 hours reading and studying it to digest its contents and truly attune. The creature can then freely modify the book’s contents, provided that those modifications advance the lore already contained within. The dark arcananomicon can also serve as a spellbook for a wizard with no page limitation on writing and copying spells.

Special Attunement. There are only two ways you can attune to the book. The old user must be dead or have given it up freely. If they give up the book all benefits they have gained from the book are stripped and they can never attune to the book again. If the user dies holding this book the soul of the user is consumed by the book and their knowledge is added to the book’s pages. A person killed in this way can only be brought back by a wish or similar magic.

Increased Mind. After you spend the requisite amount of time reading and studying the book, your intelligence score is increased by 2 to a maximum of 30. You also gain advantage on all intelligence saving throws.


Obscene Lore. You can reference the Dark Arcananomicon whenever you make an Intelligence check to recall or understand information about necromancy and dark arts. When you do so, double your proficiency bonus on that check. Additionally you learn the Magic Circle and Protection from Evil and Good spells. They are always prepared and do not count against the number of spells you can have prepared. When casting these spells you can add monstrosities to the list of creature types you can defend against with those spells.

Command Undead. While you are attuned, you can use an action to cast the Dominate Monster spell on an undead target (save DC 21). After you have cast the spell you can’t use this feature again until the next dawn.

Potent Spell Casting. You gain a +2 to your spell attack modifier and DC. Also when you roll damage with a necromancy spell you can add your Spellcasting modifier to the
damage.

Spell Stealer. As a reaction you can try to cancel a spell that is cast within 30 feet of you. You must make an ability check using your spellcasting ability. The DC is equal to 10 + the spell’s level. On a success, the creature’s spell fails and has no effect. When you cancel a spell with this feature you can on your turn cast the canceled spell without spending a spell slot even if you do not have the ability to cast the level of the spell. You can use this ability twice per long rest.

Arcane Security. The Dark Arcananomicon has different means of security which are set in place when someone other than the attuned person tries to read it. The book is under the permanent effect of the Arcane Lock spell which can only be opened by saying the phrase “Death before life”. The book also gives off an alarm inside the attuned person’s head when someone tries to unlock it. The pages of the book appear blurry to anyone but the attuned creature. If another creature attempts to read the pages, they must succeed on a DC 21 intelligence check to obtain the information from one page.

Spell Holder. The book can hold a spell of the user's choice. The spell can be triggered by something declared by the user just like the hold action. If the spell needs components they are used when the spell is put into the book. Casting a spell into the book uses a spell slot.
