Just taking the legends you get and putting ones together that have synergistic effects will go a long way toward climbing to floor 200-250. Focus on a single element and try to get something with Ignore Resist, you'll fly to 200 easily.
Something like the "poor man's green garden" where you put on everything you find with Druidic or Plagued, and change your elements to poison on anything that's not already that.
Also, do bring your hireling. Having that extra damage helps, plus when you have a hireling the gear is (mostly) restricted to just the classes you're running. And it auto-sorts gear so you get wizard gear in your inventory and your hireling gets his class gear in his inventory. And you get an extra 100% item drops!
The sweet spot for early farming is the 180-200 range. Once you get comfortable there, you can work on getting the luck/gold/item gear for your optimal farming set.
