Courage, one of the five Royal Virtues in Metaphor: ReFantazio, is a measure of the main character’s bravery and willingness to face danger. A higher Courage stat unlocks unique dialogue options, deepens relationships with your followers, and even grants access to special quests and activities. It’s a great virtue to focus on because it usually lets you say things that the protagonist would be too scared to say otherwise, and those situations make you feel like a real hero.
