The four printable chambers in this product are, like all similar LZW products, richly illustrated and evocative. The “cover” image might be taken to imply that you can use the chambers inside to build a complete small dungeon, but you’d need to connect them with corridors (not included) or set the crypts in a graveyard or supply a central chamber of some sort. Chamber 4 features some minor customizability using PDF layers (you can turn a pentagram and fog layer on and off). The tiles are not modular; you can’t really mix and match. These maps would be great on your table once—and then you probably don’t want to revisit them anytime soon, as they are very distinctive and would get trite if overused (hence four instead of five stars), but the price is reasonable even for one-off use.
