Manual of Gainful Exercise

Wondrous item, very rare

• Weight: 5.0 lbs.

This book describes fitness exercises, and its words are charged with magic. If you spend 48 hours over a period of 6 days or fewer studying the book’s contents and practicing its guidelines, your Strength increases by 2, to a maximum of 30. The manual then loses its magic, but regains it in a century.
