Cure the Scourge

Objectives
Collect 20 Withered Tusks.
 * Withered Tusk

Description
Far more effective than killing swarm after swarm of Scourge is finding a method to prevent living creatures from ever being turned into them. I have an idea for a fine powder that, when inhaled, may stop the entire process.

I need withered tusks off the unliving Quilboar here to make this powder. Bring me an ample amount, and we may be able to stop the Scourge's growth for good.

Progress
Do you have the tusks?

Completion
I have faith that this substance will prevent many future headaches. Thank you,.
