Anderak 4 is called The Darkroot Caves.
Kill 5 Darkroot Tender
Kill Mold Master Gangli
Loot Gangli's Poisoned Roots
There are three other confused steps as well...
One says kill 20 Darkroot Warriors... but the status counter shows only 18
One says Kill 5 Darkroot Shaman... but the status counter shows 3
One says kill 5 Darkroot Vineherds... but the status counter says 3
Right now I assume the last step is to take the root back to Anderak.
The Herders are surrounded by Darkroot Vineshards... tnhey will mezz and root. A Mezzer is key cuz they hit me 1.2K (L75, full mitigation Paladin).
Gangli and is surrounded by Darkroot Orchids. He and the Orchids are permarooted.
The Orchids hit me 1.2K and Gangli git me 2.6K.
