From publisher blurb:
Let the Spirits Arise Within You!
Occult Character Codex: Mediums contains 20 detailed medium stat blocks, including both ordinary mediums using their powers to let eldritch spirits of legendary heroes and villains to wield their powers by opening themselves to their spiritual influence and channeling the power of haunts and spirits alike through trances and séances, as well as relic channelers and reanimated mediums alike! You'll find medium humans and halflings, dwarves and elves, but also stranger races like centaurs, aasimars, and monstrous berbalangs, running the gamut from good to evil and all points in between. With the Occult Character Codex, you'll have an entire arsenal of medium characters waiting and ready to blow your players' minds!
