There was some talk about a lack of fluff in the discord for the hulk, so i wrote another version of them.
Design: Imp Hulk V. 2
The imp hulk is designed to be a line breaking unit for our army. The are related to the imps, but have several unique defining features of their own. First and foremost, they are quite a bit larger and stronger than the average imp. perfectly upright they would be almost 7 feet tall, but they have a hunched posture, and occasionally leaning forward into knuckle walking like a gorilla on thier well muscled forelimbs. They have a thicker hide as well, brown instead of red. They have exaggerated adrenal glands which makes them more difficult to use in formation, but absolutely devastating during a charge. Compared to an average imp, they have reduced intelligence as well, to help offset the cost.
In battle, they are designed to function as line-breakers. A first wave of heavily armored hulks shatter enemy formations and incite fear. This is then usually followed by a wave of fireballs and a well ordered charge by the infantry. Such shock tactics are designed to shatter defensive formations, route enemies, or create breaks in the line for our (currently non-existent) cavalry to charge through to the enemies rear ranks.
Outside of battle the hulks are strong workers, excellent in manual labor positions and methodical work. A common profession for the hulk is farming where they act as both plow horse and farmer together. They are also known to work as lumberjacks, quarrymen and dockhands among other such professions. While not the most dexterous of individuals, thier low intelligence keeps them focused where others might get bored with a task. As long as they are treated fairly and remain calm, they are content and productive workers, just as happy moving freight as they might be breaking bones on the battlefield.
(Fake edit: looks like you already got some fluff out while I was writing this. I have enough unique features in this though that i'm going to post it as it's own design. I actualy thought about including larger claws/horns in this one as well, but decided against it. I would rather the hulks use large weapons that go hand to hand. Claws and strength may be great against unarmored units, but I want hulks to still be effective if they come up against units that are heavily armored, or just as big as they are. (or bigger) Imagine those guys using greataxes with that strength, and wearing heavy armor themselves they would be near imp-enetrable. )
