Field Researcher

Your notes on the anatomy of different creatures of the realm are so extensive that you know practically anything you have notes about.

-You have notes on every type of creature. These are stored in a notebook and can be lost if the notebook itself is misplaced, stolen, or destroyed. You can replicate the notes for 250gp of ink and paper. Every long rest, you can choose one type of creature to recall in combat.

-For 1 minute, you can examine any type of creature, taking notes on its anatomy, strengths, and weaknesses. You have advantage on Arcana, Nature, and Medicine checks regarding the creature in question, but you must have the creature's type selected to use this benefit.

-In combat, as a bonus action, you can recall information about the type of creature you have selected. You have advantage on one attack roll made against that creature. You can do this a number of times equal to your proficiency bonus.
