when u fear a warlock throught the invisible walls at the way to the Brutallus dummy on the Isle of Quel'Danas and get 2 other players behind the walls (e.g. a shadowstep rogue get easy behind them) u can port 37 more people to the dummy u can kill him easy.
he has the same amount of hp and does the same damage, so he adv. drops the loot from brutallus. if anyone want to try it out, or have the people to do that , hf
