Notice is a hero’s general awareness and alertness. It’s used to sense sights, sounds, tastes, and smells, spot clues, detect ambushes, spot hidden weapons on a foe, or tell if a rival is lying, frightened, happy, etc.
Success conveys basic information—the character hears movement in the forest, smells distant smoke, or senses someone isn’t being completely truthful.
A raise grants more detail, such as the direction of a sound or odor or what topic a person is avoiding or lying about.
