The Grimoire

Your patron is an ancient and sentient tome, or an entity that was sealed within the tome’s pages long ago. Through this tome, your patron communicates with you and grants you the ability to read and understand the bizarre symbols and scrawlings that litter its pages. Within this strange and alien language, you’ve been shown forbidden secrets; secrets of power and magic, their true limits untold. In exchange, you’ve bound yourself to your patron’s indecipherable intelligence and dominating will.

Expanded Spell List

The Grimoire lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Eldritch Tome

At 1st level, your patron bestows upon you an Eldritch Tome, which allows you to tap into ancient and forgotten knowledge. This tome can take whatever form you wish, such as a simple notebook, a messy collection of notes and scrawlings, or an ornate stone tablet.

If your Eldritch Tome is destroyed, or you happen to lose it, you can perform a special ceremony to receive a replacement from your patron as part of a long- or short rest. After a new Eldritch Tome is created, the previous one is destroyed. When you die, your Eldritch Tome vanishes, returning to your patron.

While your Eldritch Tome is on your person, you have a pool of d4s equal to your warlock level. Whenever you or a creature within 30 feet of you makes an ability check or a Wisdom, Intelligence or Charisma saving throw, you can expend a die from this pool and roll it, adding the result of the roll to the check or saving throw. You regain any expended d4s at the end of a long rest.

Secret Pages

At 6th level, you’ve discovered hidden pages within your Eldritch Tome containing writings that unlock new abilities. You gain the following features:

Ghost Writer. You’ve learnt how to temporarily trap a creature’s mind within your Eldritch Tome. By spending 10 undisturbed minutes with the corpse of a creature and your Eldritch Tome, you can transfer the mind of the creature to one of the pages within your tome. To do so, the creature cannot have the undead or construct creature types, it must have an Intelligence score of at least 8 and it cannot have been dead for longer than 7 years.

While a creature’s consciousness is held within one of your pages, you can write on that page to ask it questions. The creature will then provide an answer to the question, but can choose to lie. The creature will have all of the memories it had in life, and is neutral to you unless it was hostile or friendly towards you before its death.

You can only have one consciousness within the pages of your Elder Tome at a time, and the consciousness is released from the pages after 7 days have passed, or until you choose to release it (requires no action by you).

Descriptive Sense. You’ve learnt how to let the eldritch magic within your Eldritch Tome temporarily enhance your senses. As a bonus action, you can focus your mind on a page in your Eldritch Tome for up to 1 hour. For the duration, you gain blindsight of up to 60 feet, as your patron describes your surroundings to you in written form on the page. You can end this ability early as a bonus action, or by taking your hands off of your Eldritch Tome.

You can use this feature once per short rest.

Hidden Arcana

At 10th level, you’ve learnt how to tap into arcane secrets hidden within your Eldritch Tome’s pages. At the end of a long rest and while your Eldritch Tome is on your person, you can choose two spells from any class’ spell list and add them to your list of known spells. You must have spell slots of a level that is high enough to cast the spells, and you can only cast them with Pact Magic spell slots. The spells count as warlock spells for you, and do not count against your total number of spells known.

You know the spells until you choose to exchange them at the end of another long rest.

Librarian’s Mind

At 14th level, your patron’s influence has hardened and empowered your mind. Your mind and emotions cannot be read or altered, and you have resistance to psychic damage. Additionally, whenever a creature makes a Wisdom (Insight) check against you to ascertain your intentions or sincerity, they have disadvantage on the roll.
