The Warrior skill Stance Mastery will allow the Warrior to retain up to 10 of his rage points when changing stances. Any additional rage is lost, unless the Warrior has allocated talent points to Tactical Mastery (Arms), which allows conservation of a further 5/10/15 Rage, (1/2/3 points). Stance Mastery must be trained or else the Tactical Mastery talent has no effect. The combination of these allows for a Warrior to retain a maximum of 25 Rage when switching stances.
