Lairs: Adventurer's Pack

From BoardGameGeek:

Are you looking to develop your dungeon crawling skills and to gain access to even more dangerous monsters and devious traps? In the Lairs: Adventurer's Pack, you'll add all sorts of challenging new content to your Lairs base game. Unique attribute cubes unlock powerful abilities, and you'll need them to overcome the original monsters and traps your opponent will have at their disposal. Add the new content all at once or unlock the boxes and envelopes in stages, introducing it gradually. The Adventure is up to you!
