Map of Gnarlroot Caves

Grimak Nailbiter

Gnarlroot Caves is the location of the quest Root of the Problem, where you are sent by Pelendethas Everstride as part of the Sharandar Campaign.

In the heart of the Blighted Grove there lies the Gnarlroot Caves, the heart of the corruption driving the plant creatures in the area to madness - dark witchcraft. The area is protected by an evil redcap witherer named Grimak Nailbiter.

Completing the quest in the Gnarlroot Caves gives you a chance of receiving one of the following rewards. You will require a Dark Fey Key to access these rewards.


Pelendethas Everstride
We may have found the source of the blight. A redcap witherer named Grimak Nailbiter is using fomorian potions to poison the great trees of the grove. He uses deep twisting tunnels beneath the trees to poison their roots.

Enter the Gnarlroot Caves and hunt down Grimak.


Enter the Gnarlroot Caves, and defeat Grimak Nailbiter in the Blighted Grove in Sharandar.

  • Raid the Glarlroot Caves
    - Go to Gnarlroot Caves
  • Kill Grimak Nailbiter
  • Collect Reward


There is a Repeatable (Daily) available after doing 3 more Blighted Grove Repeatable Quests. Note however the quest is not required to run this dungeon. You can run it simply by going in the entrance as many times as you wish. You can also open the chest at the end as many times as you wish - given you have a Dark Fey Key. The quest is only necessary to gain the rewards listed on the right in the infobox.

Difficulty Scaling[]

This dungeon features automatic built in difficulty scaling. If you enter solo, or with up to 4 players - you'll get the regular solo version. If you enter with a full group - you'll get a more challenging 5 man version.
