The mobs packs between Kypari Ik and the wall to east (horrid march etc)
Few things I think you should have:
- Decent gear and class that can handle big packs of enemies (lvl90) Im running it as 460 Guardian Druid. and I haven´t died at all. It will face elites with 1,200K hp approx but they are not hitting hard and buffs help lot.
- Buff from Klaxxi´vess Xaril the Poisoned Mind: Raining Blood - Unstable Serum - Spell - World of Warcraft
- Buff from Klaxxi´vess Skeer the Bloodseeker: Battle Hymn Battle Hymn - Spell - World of Warcraft
- ( you will end up with alot of the following )
- Dread amber shards what you can turn in for Klaxxi reputation
- Lots of green items
- Windwool cloth
- Motes of harmony
Kills/hour are 280-400 it depends bit how mob packs spawn. loots were 100/hour on my last run. Motes seems to come in nicely and shards too, way lot more than Zan´vess, allthought you kill lot more so you might die easier.
*edited* Wanted to also say that for Unstable Serum you need to be revered to have that klaxxi unlocked. Otherwise you can always try Using these two combos. Battle Hymm & children of the grave
