Sure.
First of course is to get the DF discorded. Then I send my doggie in to fight the DF and mount an ethy. I usually can just heal with magery, but occasionally I have to run in and throw some aids on it.
As the DF spawn comes I provoke it onto the the DF. I mainly only provoke the mummies, skeletal knights, lich lords and rotting corpses. Any of the lesser creatures I either ignore or just kill with a fireball or using Staff of Pyros.
Sometimes if alot of LL's and RC's spawn I'll provoke them onto each other first since the failure rate is alot lower than provoking onto the DF. Then as I have time I'll provoke them onto the DF. RC's are really the only thing that once provoked onto the DF are going to last more than a couple of minutes.
It does take awhile but it's fairly easy to do. The only times I die is if I get real unlucky and a LL gets me.
