Oh, so now Aldhagrimm is giving me orders? I know she's the matriarch of an entire race and Edgar's grandmother, but... Very well. If you defeat 5 Yeti Hulks, that should produce enough refined blood for a full bottle.
I assume this means there are no hard feelings from the old woman about that time I tried to kill her. Or that other time I tried to kill her. Or when I called her an unwashed cretinous old biddie. I'm somewhat proud of that insult.
