I don't think I've read that story...what did the svartalf do in it?
Going by a glance at the wiki, Flesh Mask is probably appropriate. Maybe also full wizard casting, with some crafting-focused Refinements. Going all-in on enchanted items can be pretty damn effective.
And then of course there are the fey standbyes. Strength, Speed, Toughness, Recovery, and Glamours.
