Formbound Mysteries
This supplement expands shapechanging play in a high-psionics setting. It introduces two psionic classes, two psionic prestige classes, a new psionic organization, ten feats, and more than a dozen psionic powers. The material supports creating formbound characters from the ground up, including options for characters who alter their forms, fight alongside animal or astral companions, and reshape the world around them. It also includes rules compatible with the Formbound and Shapechanging rules from earlier supplements.
