also dont expect to find a lot of uniques and other good items on ur first or second run. The pits arent like meph or andy where they will most likely drop some kind of rare/set/unique. In meph or andy, u'll be able to find a lot of mid/low end items and sometimes higher end stuff.
You'll find mid-higher lvl items in the pit but you have to be patient. If you find one unique in a run, consider yourself lucky.
