Clockwerk goblins are poorly-made soldiers that explode after a set period of time. It is obviously of inferior workmanship: It bounces up and down, the sounds of rusty gears echo from within, and steam shoots from crevices. A large key turns in its back, making it look like a giant wind-up toy with a red hat and goggles. It swings a spear with its left hand.
They are some of the first creations an intermediate goblin tinker makes when he experiments with self-ambulatory devices. They are useful as an exercise, but not so much as real soldiers — the design’s original specifications seem in error, for after a short period of time, the goblin shuts down. Rather than redrafting the blueprints, some enterprising goblin in the past made just a few adjustments, so that rather than shut down the clockwerk goblin explodes, making it sort of a mobile bomb.
Clockwerk goblins go where they are programmed to go. What this usually means is that the tinker sets up an inert clockwerk goblin (or row of them), and, when the time is right, activates it. The clockwerk goblin bumbles along in a generally forward direction. After a period of time (which the tinker sets when he activates the goblin), the mechanism detonates. Clockwerk goblins are simple devices. They are capable of following specific targets, moving along the ground, making up to 360-degree turns, and swinging their spears, but that’s about it.This section concerns content exclusive to Warcraft III.
Like Goblin Sappers, you cannot carry Clockwerk Goblins in a transport. Otherwise you would load up transports with them and blow up entire towns and that wouldn't be any fun for the person being blown up, but what do you care because you'd be having fun blowing people up! Anyway...it's not allowed...
