Alchemist's Lexicon

This nonmagical easy-to-navigate book was published with the hope of inspiring budding alchemists to pursue the burgeoning art of alchemy. However, since the book revealed secret Brelish techniques, most copies of the Alchemist's Lexicon were rounded up and burned during the Last War. Only a few copies remain in the world.

If you make an Intelligence (Nature) check to discern the alchemical properties of a nonmagical substance, you can choose to spend 1 hour consulting this book to automatically succeed the check. If you are proficient in alchemist's supplies, you instead only need to spend 1 minute.

The time required to craft potions while consulting this book is halved.
