There are several things I like about this series. First is that the items are all simple to add to your game. There are no vast descriptions of each item, so the GM can pretty much write his or her own backstory for the items. Second there are no game killers. None of the items so far have the capability of killing your campaign. The third thing I like concerms this product specifically, new non-combat magic items. By that I mean new non-weapon magic items. I like including these types of items in my adventures. Last but not least is the price. The money spent is well worth it.
