Agitator is a specialization of the Diplomat Career.
The Empire’s main weapon, more effective than all of the incredible firepower at its disposal, is fear. Fear lets it maintain order and authority over the countless beings in its thrall. The Agitator’s primary goal is to remove that fear and replace it with anger, or courage, or a sense of righteousness – whatever it takes to get the people to rise up, take up arms, reject tyranny, and restore freedom and justice to the galaxy. For Agitators, Coercion, Deception, Knowledge (Underworld) and Streetwise are all added as career skills.
Agitators can be found in the Age of Rebellion Core Rulebook.
