I have a lead on an even BETTER source of hides, if that's even possible to believe! In the northern parts of Feralas - deep within Rage Scar Hold - are another throng of yetis. They're much tougher than the ones you dealt with before, so if you're up for a bigger challenge you'd best be on your toes!
I would reward you handsomely for a stack of ten of their hides; bring them to me here, and we'll finish our business.
Excellent, excellent! These are going to work out incredibly well - I can already tell that they're going to be much harder when properly cured.
Thanks again for your aid, <name>. Here - please take one of my latest creations.
