Each location type will be a d66 roll and additional sub tables for Magical or Odd items will exist as well. So a kobold might have Pockets listed as its treasure type, and most of the rolls will provide mundane items or a few coins. Yet there is a chance something unique, cursed, or magical might be found. The chance of finding better treasure and the type of items found change with the notation of pocket, pouch, pack etc.
To me this is a more logical presentation/classification of treasure and finding mundane things may add to player creativity in game as well as making finding magical items more special and unique.
In addition my wife is starting the cover for HOW so I hope to share a sketch or two in the days to come. I am removing the HOW beta rules from download, there are a number of changes which the beta rules do not represent properly.
