Within these sets of tomes lay the innate knowledge and training to perfect yourself in a specific field you may encounter during your life as an adventurer, or to truly master your art within it.

Written by a long forgotten Mage, various times exist, each corresponding to a different skill (athletics, stealth, perception).

Over the course of a week, you may read and practice the instructions detailed within the tome, furthering your own understanding. You gain proficiency in the skill corresponding to the tome. If you would already have proficiency, you instead gain expertise.

Once used, the magic within the tome becomes inert for a century, and you can never benefit from another tome of advancement again.
