The of the game guide has been extensively rewritten to better clarify changes to the treasure system this season. The section now properly addresses treasure tags, equipment locations, performance requirements, valuables, the new loot system, and all manner of ways to create and manage treasure. Note that none of these are rule changes per say, but much of he new information has never been properly codified in the game guide like this.
With a subject this big, chances are good that I left something out, so please let me know if you notice anything that isn't covered.
