Shellfish  

A minimum Gathering skill of 190 is required to harvest this node.

This special tradeskill quest resource node can only be seen by players that have one of the quests from the Grobb Daily Supply Tasks Mission Group, and are found along the edges of the pools in Innothule Swamp just outside of Grobb.

Each harvest yields 3 grobb shellfish. Each node may be harvested once.

A complete guide to harvesting can be found at A Harvester's Guide.
