Index of Potions

This massive book provides a complete list of every single type of potion, describing all their properties and effects to include what manner of container they are likely to come in. It does not tell how to make potions or even what their ingredients are, it is only good for identification purposes. The book itself is non-magical. There are several copies of the book in existence, but they are rare and highly prized by magi, sages, and the like.
