Sunscorched Shells

My colleague, Furen Longbeard, made a discovery which I am eager to test. I wish to try it on a new armor that I am researching, for I believe Furen's techniques will produce superior results.

Will you help me? If you gather what I need to make the armor, then I will make an extra piece for you.

I need the sunscorched egg shells of the Highperch Wyverns who dwell at Highperch, in Thousand Needles. Search for the shells below their nests, and return to me when you have a sufficient amount.
