The master reward book is a gift from Xuan once you have completed the Master jack of trades aura's regular skilling. Once the aura depletes on its own or the owner removes the aura after he has trained in 15 different skills, they may get the book, but will not be able to receive another book until they use the first one. This book works similar to an XP Lamp or Penguin Points in the fact that players specify a single skill in which to receive their bonus. The formula for the experience gained is $ y = 2\left(x^2-2x+100\right) $ where y = Experience earned. It gives 50% more experience than the reward book from the regular jack of trades.
