Trivia

• The name of this trait is a reference to ArenaNet's explanation on changes to the Scrappers Gyro skills in the October 18, 2016 game update, where they cited "purity of purpose" as the reason for the change. Neither the changes nor the explanation itself were received well by the community and quickly became a joke for misguided decisions in Engineer balancing.
