Quest:Gathering the Cure

Gathering the Cure

3 Earthroot can be found in the pirate's chest in the far south camp (closest to Northwatch Hold), just south of where you get the Telescopic Lens and next to where you get the Shipment of Boots as per the Stolen Booty quest.

Earthroot can also be found in the Wailing Caverns. In particular, two can be found in one chest in WC.
