A Triumph of Gnomish Ingenuity

Objectives
Speak with in New Tinkertown.

Description
We will need all the weapons, inventions, and soldiers we can get in order to defeat Razlo Crushcog and his followers.

Over to the northeast, you'll find Engineer Grindspark, one of a new generation of brilliant gnomish minds. Why, he hasn't had an explosion in over three prototypes!

But enough bragging. Engineer Grindspark is working on a bot he says will help clean up the toxic airfield. You should introduce yourself to him and see if he needs any help testing it.

Completion
So himself has heard of my little project? Splendid! I've almost finished my latest prototype, but maybe you can help me chase down those last few parts.
