In-Game Text
"Any old idiot can fight, but knowing how to throw a punch or two doesn't make a warrior out of anyone. To become a warrior, you need the courage of a bear, the abandon of a boar, and the cunning slyness of the fox."

By mastering the Warrior Spirit, you will be able to throw yourself at your opponents with force and fury. Stuff like that always helps when you want to get a point across.
