A magic item of therapeutic qualities:
Stone of Relaxation
A stone of relaxation, if kept on one's person such as in a pocket or a pouch, will keep one free of stress and anxiety, and will grant a +4 bonus to saving throws vs. fear-based attacks. If held in one's hand, it will extend the zone of peacefulness in a 4 cubit* radius. If rubbed, it will imbue one with immunity to both fear and insanity for the duration.
Like other magic stones, a stone of relaxation has no standard size, shape, or coloration, and will only activate when in close proximity to a living creature.
