Hi, Chaos <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />

Please, tell me, which version are you playing? I'm a bit concerned about a dungeon without enemies..
About not finding a boss enemy and/or a quest item => dungeons, bosses and items are generated randomly, so this is ok, if you don't find a solution in one of the end levels. Solutions are in the 3rd level always - but not in everyone.

Possibilities:
Several enemies/items in the 3rd lvl
None
One
