|Description||This extensive book describes many aspects of the building process, and will reduce the duration of one building task by 8 hours.|
Books are Acceleration items which can be used to decrease the duration of one construction task (either upgrade or downgrade) by 8 hours. If the task has less than 8 hours to complete, the item may still be used. However, it is not advisable to do, as the remaining time from the item is wasted.
This item is fairly common in high-levelled wildlands, but only one ever drops at a time.
