A layered maze where navigation is the hard part. After killing the four Fanglords (Anacondra, Cobrahn, Pythas, Serpentis) you escort Naralex's Disciple, and only then does Mutanus appear.

Before you go

The Fang druids cast Healing Touch, so split interrupts and make sure every cast is stopped.
Poison and sleep dispels prevent most wipes.
The five 'of the Fang' pieces (Embrace of the Viper) drop from the four Fanglords and trash. A druid wearing all five turns into a serpent in Cat Form, a 5-piece bonus missing from the tooltip.
Raptors call nearby mobs when low on health, so clear around them first.
The map is flat but the cave is layered, with drops you cannot climb back up, so it is easy to get separated.
