The Magic of Gemstones

GENERIC VARIANT UNKNOWN RARITY

An old tome barely holding together, its pages yellowed and crumbling to the touch. It lists various types of gemstones and how to best use each one for magic. Some of the pages are so damaged you can't even peel them apart, and the rest of the tome is written in an older version of common that is troublesome to decipher. But with time, you can transcribe its contents.

On the inside cover is a faded signature, "Corben Copperspring"
