The Epic Story Boost, also known as the 12x XP Event, was a server-wide event that augmented the Experience points earned from all class-specific story missions. Accounts that qualified for the promotion could advance through story missions with an experience point multiplier of 12. The most recent event began on May 4th, 2015 and ended just before the official launch of Star Wars: The Old Republic: Knights of the Fallen Empire on October 27th, 2015.
