Yes, Steve Winter posted on this at one point, explaining that because HotDQ was written before the release of the PHB (and even further in advance of the DMG treasure rules) they went with a very conservative approach to treasure, allowing individual DMs to add more if needed. (Unfortunately, this worked badly with its use as a D&D AL adventure!)Anyway, has anyone else noticed the lack of magic items within the adventure? I know that the adventure was released prior to the official release of the rule set and I can't help but think that this had something to do with this missing aspect of loot.
That said, we noticed it wasn't quite as necessary in this edition to have as many magic items.
