Adventurer's Journal

This small, leather-bound old pocketbook served as a journal for notes of an adventurer once upon a time. The pages are filled with shorthand and quick sketches of encounters the adventurer experienced. There are additional pages inserted here and there and items are taped onto some pages. While it does seem rather helpful, it isn't always the most accurate, since the adventurer wasn't an expert in every creature they came across. The notes are sometimes difficult to decipher. However, there are notes on what the adventurer learned about the creatures, and occasionally on different locations they explored, and knowledge is certainly contained within these pages.

When you encounter a creature, you can use an action to make a DC 12 Wisdom (Animal Handling) check. On a success, if it is a creature the adventurer encountered, you find the page it's been written on. It has the name, a picture, and a short informational paragraph about it. The entry is only on the species of the creature and does not mention any specifics on the individual. To determine if the creature has been noted in the journal and what information the previous adventurer was able to compile and whether they were accurate, The DM will check the creature's CR
