The Ars Transmutica
This thick tome is bound with hide of some blue-scaled creature and laced with golden thread. The cover is filigreed with a silver & platinum emblem of the wizard, Amalzain, a transmuter of mysterious but legendary acclaim. Histories and books of lore cite Amalzain as the foremost leader in experimentation with transmutation magic.
The interior of the tome is riddled with notes, diagrams, patterns, marginalia, etc. that delve into the mysteries of creation and changing the nature of reality through transmutation. There is rarely a spot in the tome where empty space upon the vellum exists. And, through the magic of transmutation, the pages will often shift and change if a wizard with the transmutation specialty gazes upon its pages.
This means, only a Transmuter can use this tome to learn its mysteries or to learn one of the spells contained within.
You must spend downtime days to learn a mystery of transmutation. You must be able to use the original ability in order to enact the mystery. For example, learning The Mystery of Stones doesn’t mean you can create transmuter’s stones if you are not yet 6th level.

There are special notes toward the end of the tome; notes about Amalzain’s hidden enclave on the Isle of Jewels, where Amalzain’s laboratory seems to be located. Why or how the Cult of Eyes had this book locked away is unexplained…
