The Insignia is a certificate that you receive from the Headmaster of your primary profession at the end of your training course in the Shing Jea Monastery. The certificate confirms that you have mastered the basic skills of your profession. To receive the Insignia you must take on the respective Insignia quest from your Headmaster, which requires you to complete a number of training courses from Instructor Ng in the Shing Jea Dojo. During these quests you will receive additional free skills, which makes this a desirable task for any player.
