stance tanking an oro farming group (which leave from deldrimor warcamp)

or hell's precipice with henchies,

stancetanking an oro group it is probaly fastest, but if you hate stance tanking (like me), i just picked up some henchies on prophecie's last mission and capped it by myself, i found it easiest that way

Er yeah... you take a left at the Ring of Fire, sharpe left at the Abaddons Mouth go straight ahead and do Hells Precipice and unless you somehow went a completely undiscovered way you can't exactly miss the boss.
