ok my build is,
Death nova, putrid flesh, animate bone minions, animate shambling horror, [spare slot for elite], blood of the master, taste of death, rebirth.
this is all available from yohlon haven or earlier apart from blood of the master. This i would suggest you unlock with balth faction then get it from any skill trader.
The use of the build doesn't matter for an elite... jagged bones rocks for it however any elite you like from death line would do fine since its not a neccasary requirement.
To use the build... raise millions of minions... caste death nova then putrid flesh when they stack round enemies... rinse and repeat.
I couple this build with a toxicity/broad head arrow ranger with epidemic and then a critical barrage assassin.
Nothing survives as long as you have minions in the first place.
Oh and if you really can't get blood of the master remember this.. with a minion bomb build its not required for them to live along time
Atts are
Max out death and soul reaping
**edit** PLEASE remember not to use putrid flesh when you have human enemies!!!!!! use taste of death to kill your minions to set off death nova instead.
