The Agrippa Grimoire is hard to define as a monster as it is a book, but one that is alive. While it can’t move it calls towards those near to pick it up and use it. The moment one casts a spell from inside the book the pact between the Agrippa and its victim is signed. Agrippa have but one goal and that is to live a life that is worth a story. For Agrippa are not only spellbooks, but books detailing stories of heroes, villains and individuals of great reknown. While these stories detail various individuals, they are invariably all creatures that have been taken over by the will of the Agrippa.

Agrippa are beings that live off of stories, being living grimoires of stories and spells. As such they have various abilities that are tied to the recording of stories and history. The most frightening of these is perhaps their limited ability to rewrite history.

Mighty Grimoire

1st-level Agrippa feature

You are protected by your patron. As a reaction when affected by magic, you raise up your Agrippa to protect you. This will cause the following:

• Instead of being affected by the spell, you gain temp HP equal to the spell's damage + your warlock level. If the spell is not a damage spell it is 5 + your warlock level instead.
• If you have expended a spell slot, you recover a spell slot.
• If it is a spell you know but have not prepared, you can cast the spell for this encounter.

You use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Rewritten

6th-level Agrippa feature

Your patron’s narrative powers have a profound effect on your body and magic. You don’t need to eat, drink, or breathe.

In addition, once during each of your turns, when you hit a creature with an attack roll and roll damage against the creature, you can magically rewrite history, forcing the creature to teleport to a location of your choice 10ft of where it stood before teleporting.

Rooted in History

10th-level Agrippa feature

By the sheer will of the Agrippa and its adherence to stories. You have resistance to being moved against your will. If an Effect moves you against your will along the ground, the distance you are moved will be reduced by up to 10 feet.

In addition, if you are hit by a damaging spell, your AC will increase by an amount equal to your charisma modifier until the end of your next turn. This effect does not stack.

Annals of History

14th-level Agrippa feature

Your open the Agrippa on a page detailing history in its greatest detail, unleashing its full potential. As an action, you start chanting the annals of history.

 

While rewriting the narrative you can do the following:

• You can change the location of every creature within 120ft of you, including yourself to a location within 120ft of your choosing.
• An amount of creatures up to your proficiency modifier will have resistance to bludgeoning, piercing and slashing damage until the end of your next turn.
• An amount of creatures up to your proficiency modifier will have vulnerability to all damage types until the end of your next turn. This bypasses immunities and magical resistances.

Once you use this feature, you can’t do so again until you finish a long rest.
