Tome of Understanding
This thick book contains tips for improving instinct and perception, but entwined within the words is a powerful magical effect. If anyone reads this book, which takes a total of 48 hours over a minimum of six days, she gains an inherent bonus of from +1 to +5 (depending on the type of tome) to her Wisdom score. Once the book is read, the magic disappears from the pages and it becomes a normal book.
