(Subclass is Thrro-Exclusive)
The first Training Dummy Thrro originally was created by a mage for commoner fist-fighters to train their brawling-skills on, after said mage had been constantly buggered for months at a time. So, he gave them what they wanted; A thrro that could handle their beatings. When reports of these Thrro retaliating reached the mage though, he, fearing the worst, went on to investigate... only to find that the fist-fighters were very happy about this development, and the Thrro also having learned to love the thrill of fist-fighting.
