From publisher blurb:
Gods oversee the cosmos. They control the ebb and flow of the seasons. They ensure that the risen moon gives way the morning sun. They apportion all manner of mysteries, terrors, and wonders upon mortals. Gods truly do govern the fundamentals of reality. But domains are those fundamentals. Air and Chaos. Earth and Evil. Fire and Good. Law and Water. When clerics choose their domains they form connections with the deepest and most powerful facets of existence. Whether something primal like the elements or the very foundations of morality, it only makes sense to offer them a chance to expand and enhance their bond. This book gives clerics a host of new options tied to their domains. This product includes three new feats and three new spells, each with customizations specific to the elemental and alignment domains. In addition, each domain describes a holy water variant that provides interesting options to clerics and other pious followers.
