From publisher blurb: Unleash the chemist upon your foes (or upon your players). The chemist is adept at using alchemical weapons and sheathing his other weapons in alchemical concoctions to smite his foes with different energies. They can improve their battle prowess with their extracts and even gain resistances to different energy types and poisons. Having access to a select number of extracts and discoveries, chemists are versatile in how they confront their enemies and resolve any conflict.
