Huntsman Leopold at Light's Hope Chapel in the Eastern Plaguelands will make Cryptstalker Legguards if you bring him the following: 1 Desecrated Legguards, 20 Wartorn Chain Scraps, 3 Arcanite Bars and 5 Cured Rugged Hides.
Part 3 of 3
I have discovered a use for the carapace of the crypt fiend. I am able to fashion an extremely light and very deadly set of armor by combining the fragments with some of the desecrated magical armors lost in Naxxramas.
Bring me the items I require and I shall fashion for you a suit of armor the likes of which has never before been seen in our world!
Do you have the items I asked for, <class>?
As you don more of this armor, you will notice that your persona is changing. You will gain a preternatural ability for killing. Perhaps, even, a lust for blood.
Let it be said that I will not be held responsible for what chaos you may invoke...
