Monk Wyvernfang Sash Quest: How to complete it after First Ruins revamp

[Monjapino]

Quest Three: Learner's Sash
Level Required: 50+
Target NPCs: restless dead, an underdark herbalist, a spiderkin
Items Needed: Bone Dust, Rare Moss, Spiderkin Silk, Thinker's Sash
The underdark herbalist spawns in First Ruins, drops nothing else, is an hour long spawn, has placeholders (Underdark Citizens, Light Blue to a 50) and is a Shaman, replete with pet, slows, nukes, dots and heals. The herbalist spawns in a miniature arboretum in the very back of a shop called More Than Mushrooms in the merchants' quarter of the ruined city.

First Ruins is not a raid zone. It's a very difficult dungeon.

This quest is supposed to be completed at high 40ys or low 50ys, but after revamp it doesn't seem to be possible.
What should i do, is this quest supposed to be that hard??

thanks
