that's a tough but fun camp. also, bards please note that not two rooms away lies the Herbalist house, which spawns the named mob, Grand Herbalist Mak`ha, that drops the Mansi Herb for necro epics. i don't think its multiquestable, but you can let them know the mob is up.
when i did this camp , i used the lull-fade trick on the new roaming mob that drops the hotzone loot. here's what you do:
load the PoP lull. target your mob and lull it twice in quick succession, then immediately fade. he'll still be KoS to you, but you can run mobs right by him and he'll ignore you for the rest of the time you're down there. it worked pretty well for me. i lull-faded the roamer and had him path by twice while i was fighting PHs. good luck on your mask, bards
