A particularly bloody encounter with the Horde has left scores of our knights fighting for their lives. If we are to save them, we must replenish our stores of a blood-staunching draft, the brewing of which requires the root of a bush called Thaliak's thumb. Go to the Dravanian hinterlands and harvest as many of these roots as you can.
Travel to the Dravanian hinterlands, equip a botanist's secondary tool, and commence harvesting.
Travel to all the specified locations and obtain the target items.
