Some of the dungeons can be pretty tough. There are two job boards, regular and outlaw, and these are where you'll find your missions. The jobs on the regular board ask you to search a dungeon and bring back a specific Pokemon or item while the outlaw board is full of, as you may have guessed, outlaws. The outlaw jobs tend to be more problematic than the regular ones but each task has a handy lettered rating which indicates the difficulty. If you like Pokemon and dungeon crawlers you can't go wrong with Explorers of Sky.
