We're nearly there, <class>. All that is left is to retrieve a few more components so that I can attune the brazier and enable it to beckon forth Lord Valthalak.
To begin I must ask you to journey forth into Blackrock Spire and slay the orcs therein. They wear bracers that contain trace metals that I will need, so I'll need more than a few to extract the right amount out of them. Then, to complete the imbuing process, you'll need to bring me a Flask of Supreme Power.
We've come a long way, <name>, and I just wanted to say that no matter what happens, thank you! You've put yourself in mortal danger to try to help the surviving members of our mercenary company, The Veiled Blade, and as far as I'm concerned, you're one of us now.
That's it then. I'll extract the metal from the bracers and imbue the brazier with these final components. Then it will be ready for you to summon Lord Valthalak, and finally return his spirit amulet to him.
You've come quite a distance, <name>, don't falter now that the end is in sight!
