Aendryth's Eldritch Compendium (2008)

Publisher's blurb

Aendryth's Eldritch Compendium is the title of a thick black tome of spells arcane, unusual formulae, and strange magic items developed and written by a mighty wizard known as Aendryth the Eldritch Wizard, or simply, "The Eldritch," who knew great renown some decades ago. Hounded by his former arcane master, Aendryth has not been seen in civilized lands for nearly 20 years. Some say he lives today as a hermit, others claim to see him now and again in disguise in far-distant ports. While many have attempted to adapt his works in that time, most have failed to capture the artistry with which he wove these spells. His friends and well-wishers hope that someday he will return.

The tome contains the Eldritch Wizard’s unique spells, as well as formulae for creating magic items and potions using the vitreous humor and other body parts of the prysmal eye, a creature of much interest to the Eldritch Wizard.
