From the publisher:
The Book of Unusual Treasures includes material collected from four of Philip J. Reed's best-selling PDFs: 101 Spellbooks, 101 Spell Components, and 101 Mundane Treasures, books I and II. All material is revised, expanded, and illustrated with original artwork. This collection of non-magical treasures is no less unique or valuable to player characters: forgotten spellbooks and tomes of arcane knowledge, material components harvested from vanquished monsters, and masterwork weapons, armor, and other items of fine craftsmanship await the appraising eye of the discerning adventurer. GMs looking for new and interesting ways to reward their players will find hundreds of items within the pages of this single collection.
