Speak to Lomac Gearstrip in Ironforge.
The device I'm thinking about is my most advanced version to date. But we'll need a special potion if it's to work. I'm thinking we might as well get the good stuff since this mission could be your last.
And for that, we're going to need some potent explosives: Nitromirglyceronium.
The only person who can make NG-5 is an old friend of mine: Lomac Gearstrip. Look for him in Tinker Town.
You talk him into making us some NG-5, I'll get to work on placement for my devices.
