SFX Skills: Enochian Theurgy
This role-playing supplement adds Enochian Theurgy, a magical tradition based on summoning and commanding angelic spirits, to modern or fantasy d20 games. It presents a flexible SFX Skills system built around existing feats and skills, supporting both high- and low-magic campaigns. The toolkit includes rules for using these supernatural abilities, feats that govern access to them, and a new Background for scholars of occult lore. The system scales for characters from 1st to 20th level while maintaining a distinct thematic focus.
