i dont know a build that can solo it
but u can do hero/hench way green farming.
i used my assassin to farm there every single boss using the orozar quest.
the build i used was b4 all the skill updates and the pve skills
so now it works even better.The new build is on pvxwiki too.
The old build was (just incase u dont have nightfall.)
A/W
attributes.
dagger mastery 10+1
critical strikes 10+3+1
shadow arts 11+1
skills
golden phoinex strike
critical strike
moibus strike
horns of the ox
way of perfection
critical defenses
wild blow
disrupting dagger
Then new build is: http://www.pvxwiki.com/wiki/Build:A/...Blossom_Farmer
Just replace death blossom with horns of the ox to have an interrupt for healing signet.
the way hero/henchway work or all henchies is:
when the boss come kill all the normal monsters try not to kill the boss.
when the boss is the last monster standing send ur heroes/henchies far
so that their names on the party window become gray.
Now kill the boss and u will get all the drops.
