“Dreadleather, with knowledge carefully reverse-engineered from ancient texts, can be worked into elderhide. It is partly a matter of advanced craftsmanship and partly a simple magic of the earth.
With the ancient wisps you caught and the materials you've captured and the research I have done, I have put together a Legendary Tanner's Kit for you. Take it to the heirloom hides of Hrul Sharptooth in Thunder Totem. The wisp will help you use the kit there to create Elderhide.”
