The reward book is a gift from Xuan once you have completed the 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 10 different skills, they may get the book, but will not be able to receive another book until they use the first one. This book cannot be banked but can be received as a free player after membership expires. In this case the book cannot be used until membership is resumed.
