The Greater Faydark quest works just fine. You got to make sure you are giving her the right combo.
The merchant Linadian, up some platforms from main lift, will make a Banded Orc Vest for you when you give her 2 legionaire shoulderpads, an orc fist belt and 10 gold.
Linadian says, 'Glad you are interested! I can create a leather vest I call a banded orc vest. It will aid you in repelling any disease and offers quite a bit of protection in battle. I will need some materials. For a Deathfist banded orc vest, I require two legionaire pads worn by the clan Deathfist, one Deathfist slashed belt, and ten gold coins. For a Crushbone banded orc vest, I require two legionnaire pads worn by the Clan Crushbone, one Crushbone belt, and one silk swatch.'
I submitted two "Crushbone Pads," a Crushbone belt, and the silk swatch, for a successful combine.
Make sure for the CB you don't give gold, make the silk swatch and give that to her with the CB pads and CB belt. NO GOLD for the CB vest
