Hunter's Grimoire

Prerequisites: Pact of the Tome

Level Prerequisites: 3rd

A new page appears in your book of shadows, dedicated to your quarry. When you recover physical evidence from a creature (a drop of its blood, a strand of its hair, a feather, tooth or claw, etc.), you can offer it to your book of shadows in a special ritual that takes 10 minutes to perform. The ritual consumes the offered physical evidence as the name of the creature from which it came is inscribed upon the page in red ink. After this ritual, as long as you have your book of shadows with you, you have adavantage on any Intelligence checks you make related to the creature.
Additionally, you can spend 1 minute examining the page to learn one of the following facts about the creature:
-Its creature type and alignment
-Any names or aliases it uses
-Its current distance and direction from you (provided it is on the same plane of existence)
-Any vulnerabilities or flaws it has
-Whether or not it is wounded
-Whether or not it is suffering from a condition, a curse, or a similar effect, as well as the nature of that effect
The page can only hold the name of one creature at a time, and you can choose whether to replace the name of the creature currently occupying space on the page each time you complete the ritual.
