Gnarsh is the matriarch of an unknown Rock Troll clan. The Tuatha Deohn enhanced her with vast amounts of Prismere, driving her insane. The Weave of Fate said that with the support of the Tuatha, Gnarsh was fated to rampage across the Dalentarth.
- Gnarsh is the boss enemy in the Old Friends, New Foes quest.
- It is advised to stay cautious when fighting Gnarsh as she has a very large amount of health and does massive damage. It is recommended to use a Greatsword or Chakrams to reduce her to 50% of her initial health, then Fateshift Gnarsh during Reckoning to eliminate her.
- Two scuttlecrabs in the arena can misdirect aimed skills such as most Sorcery.
- The initial cutscene of Gnarsh advancing also seals the arena in which you fight her. This can also cause summoned Fae Gorta to be locked outside.
