This is the thirteenth set of plastic miniatures released in the D&D Miniatures line, and has the loose theme of "things you might find in a dungeon." Visually, this set's packaging looks a lot like the previous Unhallowed set, to the point I had to doublecheck I hadn't ordered one of those accidentally. In earlier editions of the miniatures line, there were reports of boxes being steamed open and resealed after the removal of rare minis; the good news is that Wizards of the Coast has made substantial improvements in packaging over the last few releases, and this set has the interleaved box openings that meant I had no concerns that the packs I purchased might have been opened already.
In terms of the miniatures themselves, I found them to be up to the higher standard of the Unhallowed and Blood War sets, and a great improvement over earlier sets like Angelfire. Unfortunately, this leads into my chief complaint about the set. I primarily use D&D Miniatures when running D&D as a tabletop game. While this set is well-executed and looks about as nice as inexpensive pre-painted plastic miniatures can be, there aren't very many figures in the Night Below set that make me want to buy many packs of it. The shadow is one highlight of the set; molded from translucent, smoky plastic, it is an excellent example of what can be done in plastic, but not in metal. Of the five epic figures in the set, two are distinctive human heroes from specific D&D settings; while they are exciting for Dragonlance or Forgotten Realms fans, in any other setting they're just another random adventurer. The three new dragons (including the epic large gold dragon) are a nice addition, and a couple of interesting mounted figures suggest some potential uses, but on the whole I found the set less inspiring than Blood War, War of the Dragon Queen, or other more strongly-themed releases.
