Wisdom is one of the six attributes that define a character, alongside Strength, Dexterity, Constitution, Intelligence, and Charisma.
Wisdom specifically “measures a character’s insight and their ability to evaluate a situation,” and it feeds into checks and defenses that reflect awareness, judgment, and mental resilience.
Mechanically, Wisdom commonly:
Boosts Perception: Noticing ambushes, hidden details, and environmental clues.
Increases Will saves: Resisting mental control, fear, illusions, and psychic assault.
Supports “situational reading” skills: Insightful social play, tactical awareness, and gut-check decisions (depending on your finalized skill list).
Modifies any class features, spells, or abilities explicitly keyed to Wisdom (for example, a mystic tradition that uses Wisdom to set DCs, or a divine-style caster ported into Starfall).
