This set contains: Technology, Magic, Earth. Ideally, there is another so-called. Triple Pack containing traps for air, ghosts, fire.
Tip: Although each case can only accommodate a rogue, rogue is caught in the menu can be between single play missions "exchange", so that it is possible to make do with just 8 crystal traps the 8 elements in the game. With the two available Triple pack can thus be catching all the bad guys.
Supplement: as already described by other reviewers: the EIA of the three packs is 15.99 EUR, and that's the (very fair) price I paid at Amazon. Individual traps (of which there are 46 different variations, incidentally!) May be obtained in the toy trade for 5.99 EUR. Some third-party sale, however, the apparently highly sought right now Triple Pack twice. Here just wait until the next shipment arrives at Amazon.
