From publisher blurb:
Exploding with Power!
Legendary Alchemists is the latest volume in our series of class-focused player supplements, this time focusing on the most versatile and unique class in the game; the experimental alchemists! This base class, introduced in the Pathfinder Roleplaying Game Advanced Player’s Guide, was a class designed to focus on explosives, self-experimentation, and a new and unique form of spellcasting through extracts. Legendary Alchemists expands even further on those concepts with a full redesign of amazing and unique customizations to allow players to fully explore their preferred area of super science. In addition, over 80 new discoveries spread across 3 unique alchemical disciplines allow characters incredible variety to create their perfect mad scientist. With over a dozen new archetypes including the martially inclined combat scientist to the bestial beastborn shifter, along with the endlessly inventive technical chymist, the psychically imbued esoterist, and the necromantic master reanimator, there’s no shortage of ways to build this impossibly versatile class!
