From publisher blurb: The Class Acts series introduce new archetypes and character options for the character classes you'll find in the Player's Handbook and elsewhere. Every PDF contains three full pages of high-quality content that gets straight to the point - no fluff or filler. Class Acts: Barbarians introduces one new primal path (the path of the Lunatic) and four new totems for Path of the Totem Warrior barbarians (the panther, sphynx, shark, and vulture totems). You'll also find two new feats herein (and they're not just for barbarians!): Menacing Presence and Sunder Shackles.
