Bring 20 Big Iron Bombs, 20 Solid Dynamite, and 5 Explosive Sheep to Nixx Sprocketspring in Gadgetzan.
As your mentor, I want samples of your work. You're a skilled engineer; there is no question of this, [player]. What I hope to do though is analyze them for ways to emphasize goblin-oriented techniques in your future efforts. I need the following: twenty big iron bombs, twenty sticks of solid dynamite, and five explosive sheep - and keep the safeties armed!
Submit these items to me and I will issue you your own Goblin Engineer Membership Card; it is required for access to all goblin engineering trainers!
