Masks of Magic & More is a small collection of magic items designed for the PFRPG system, and 0.99 is a small price to pay for 10 new items. However, I have some issues with the details within. I think that most of the items are overpowered for their rated cost, particularly (as one other reviewer notes) the Mask of Powders. Hand this to a player and they will quickly bypass much of your hard obstacles in a spectacular Holi-like celebration of their newfound power. That said, there are gems in here. I love the Bag 'o Bones. It's a worthwhile addition to most any campaign.
The aspect of this supplement that simultaneously pleased and disappointed me the most is the intro flavor. The narrative welcoming the reader to the shop is completely enticing; and then it ends. I believe that this unfortunately weakens the potential for this supplement. Upon reading the introduction, I began to envision a complete magical shop with a wacky NPC proprietor who could guide me through the various artifacts he had to offer. Instead, the remaining pages were relatively banal descriptions and stat blocks for the magical items.
So, I applaud a solid effort, but at the end it left me wanting. 3 stars.
