From publisher blurb:
Exploit your wildest emotions with the powerful maniac!
Maniacs are reckless arcane spellcasters that enter into an altered state of consciousness called rave. While in a rave, these rash enchanters draw upon a set of primal forceful emotions rooted deep in their psyche.
Burning emotions to fuel their magical abilities, maniacs harness powers that other arcane practitioners consider unreliable if not outright dangerous. Often ostracized by society and treated as lunatics by their peers, maniacs seek out extreme situations in which they can explore the full emotional array, drawing them towards a life of adventuring.
Included in Maniac Character Class:
The maniac character class, a wild 9th level spellcaster that harnesses emotions as fuel.
20 emotional raves for the maniac to exploit.
5 Maniac archetypes: the affector, fractured soul, fury, korybant, and tempermentalist.
7 favored class options, 3 magic items, and 2 maniac specific feats.
