Tome of clear thought

A tome of clear thought was a magical book that contained exercises to supernaturally increase its reader's intelligence.
==Description==
Tomes of clear thought were heavy books that contained exercises designed to improve the reader's memory and logical thinking. Contents of these tomes varied. Some contained a selection of esoteric and studious works of literature. Some works involved obscure mathematical or algebraic formulae, or even books that contained information on inter-planar biology.
==Powers==
Charged within the book's words was a powerful magical enchantment. If the reader completed the book within a period of 6 days, an activity that required a total of 48 hours of reading, the reader was endowed with a substantial improvement to mental capacities, including the ability to further extend them beyond natural capabilities.
Once the book was fully read, it spent its magical power and became an ordinary book, or disintegrated. However, the book recharged its power after one century.
