Secrets of Theurgy
This fantasy roleplaying supplement expands the mystic theurge, a class that combines arcane and divine spellcasting. It presents three additional theurgic paths—elemental theurges, the lord of undeath, and the theurgic lorewarden—along with the hierophant theurge. The book also includes theurgic feats, magic items, and options for adventures centered on theurgists and their churches. Reduced-power variants and rules for limiting the power of the core class provide alternatives for campaigns using different approaches to theurgy.
