Extract 5 Elemental Power for Chief Engineer Trep at Area 52 in the Netherstorm.
Darn it, that didn't do it!
Ok, I've got another idea! I had Xyrol whip up an elemental power extractor. I'm not certain exactly what this power will do, but I know that I can use it.
The sundered rumblers and warp aberrations on the ledge of the Crumbling Wastes to the south have just what I need for the engines!
The extractor will change the form of their power into something solid that you'll be able to gather up after you've defeated them.
