Whats a good build for R/Mo Farming?

I have been farming with my bro and i wanted to go solo but i need a good a good build plz can u help me??

I would say R/Nec would be better to be able to solo eoe bomb the grawl. Depending on monk secondary is alot of energy usaage, unless you can farm the undead with judges insight.

A guildie of mine used to run the R/Mo from here... said it worked, but I never bothered to try.
