Pathfinder Campaign Setting: Planes of PowerPaperback, 18 October 2016

The elemental forces of air, earth, fire, and water are among the most powerful in the multiverse, forming the basis of the material world and giving spellcasters and creatures capable of wielding them immeasurable influence. Now players and Game Masters can harness these powers for themselves by exploring the elemental planes--entire realms of existence dedicated to the four elements--in Pathfinder Campaign Setting: Planes of Power. Each of the four elemental planes is fully detailed like never before, with advice on adventuring in their harsh environs, new spells and character options, location gazetteers, and a thorough examination of a major settlement that offers a welcoming landing site for travelers from other planes (such as explorers in the Pathfinder Society Organized Play campaign).
