From publisher blurb:
Many adventurers go through their careers without ever encountering a cursed magic item. Sages speculate that the appearance of cursed magic items is the result of random chance or a misstep in the delicate creation of a magic item. Many of these so-called mistakes are intentional, crafted for the express purpose of causing fear, uncertainty, dread, or vengeance.
Athenauem Arcane: Cursed Items is a 15-page PDF detailing 10 cursed items. Also included are creatures, creature templates, and spells.
