From publisher blurb: Advanced Archetypes offers 21 (22 if you count the Rakish Villian) new archetypes for your gaming table! These 'advanced' archetypes modify your class more than your typical archetype! They were inspired ones like the Huntmaster Cavalier, the Vivisectionist Alchemist, the Zen Archer Monk, and the Archaeologist Bard that completely change the way you play a class!
