This quest is not available in game.
Bring Malyfous Darkhammer 6 Enchanted Thorium Bars, 2 Essence of Fire, and 4 Star Rubies. You will also need to turn in your Unfired Plate Gauntlets.
By Thaurissan's beard!
Where did you find them?
More importantly, are you willing to part with them? Naturally, I would pay you for such a noble gesture.
I'll tell you what, <name>. If you give me those unfired gauntlets, I will teach you how to make a set all your own. All you need to do is collect the parts for me so that I may narrow down the exact recipe.
Do we have a deal??
Here's the list of what I need, I'll front the non-enchanted thorium myself since you're supplying the gauntlets.
