Nehpek Farming?

I have tried a 4 man team with 3 heros and me. I brought along Zhed as searing flames nuker, Dunkoro as WoH and Koss as Tank. That did not work so I tried being a MM. I killed him 3/10 times.

What I am asking is is there a way for me to solo him with a ranger or a necro? If not, what should i do, should I bring so hench and kill him and keep trying till I get his focus?

I have tried to go 55 with my necro, died in a second. My ranger got killed by the other skree (too many interrupt).

Try Seaching him on wiki, it will show you his skills etc..then think of away of countering them
