Goblin Tinkerer Bench is a Greenskins military recruitment building in Total War: Warhammer. A few Goblins have a base understanding of concepts such as physics - much to the disgust of their fellow Greenskins!
Background
While most gobbos - wisely - don�t like to let on to their larger cousins that they are in fact a great deal brighter than their Orc overseers, there are a few that like to tinker with stuff. These Goblin engineers rarely receive the same respect their peers get and eke out a living on commandeered benches, out of the way of passing Orcs who can�t resist punching the speccy gits.
