The run with derv can be done quite similar, but with a ball of both, rangers and warriors.
You need to replace ebon escape with mystic vitality to increase your survivability.
For the run, you can use the same technique like mozo and use the rock to camp near the Captain (if you stand behind the little rock, you wouldnt get any dmg).
When the quest is available, just take it and shadow step into the rangers. With a little luck, you get a nice ball that can be killed in seconds
But I'm not sure about the anti-farm system that invokeur mentioned in this case.
