These pieces are made to be placed on top of the other Copper Dragon sets, primarily the Dungeons Sets, rather than the Cavern Sets. The traps featured are nice, and primarily the standard types. To spring them on your hapless PC"s, just pull out the appropriate trap (fire jets, lightning bolts, slime fountains, pit traps, or...), and place them over the appropriate floor/hallway section, beneath the PC figures. A fantastic addition to the other Copper Dragon sets. Cheers!
