From publisher blurb: Underworld breezes carry spores from far-flung fungal forests elsewhere in Aventyr’s endless caves and many are steeped with magic—some druids and spellcasters learn to empower themselves with the mushrooms, unlocking their wild potential. With flurries of exploding caps, trances that enhance their spells, and secrets otherwise unattainable to magic users of their sort these mages of nature are some of the most fell survivors in the Underworld. This new prestige class and the Mushroom domain are designed for use in Aventyr (AdventureAWeek.com’s campaign setting) but are an exciting addition to any instance of the Pathfinder Roleplaying Game!
