From publisher blurb:
Lost Artifacts of Greyghast is a magic item compendium for 5th Edition fantasy role-playing. This enormous tome is full of hundreds of unique and deeply storied magical artifacts--each with special backstories, "ready for your campaign" origins, special attunements that drive sidequests and gameplay activities, and fun mechanics that won't break your game or bore your players.
This book will be a cornerstone of any DM's table, a real go-to reference for the right magical treasure for your game.
Inside you'll find variant rules to make magic item identification smoother and more rewarding for "knowledgeable" and "smart" characters, dozens of tables and indices so you can look through the whole catalogue in different ways (alphabetically, by type, by recommended class, by complexity, etc.), and gorgeous custom illustrations from some of the most talented fantasy artists on the scene today.
