Pets:
Remember the IMPORTANT cageapults? This is important because the hive keep slaves. Simply take a caged prisoner to the slavers podium. Now bring 1 chain, 1 metal and 1 leather to the podium. You now have a (civ name) slave. Slaves are classed as pets and are given menial tasks like (stray elven woodcutter) slaves can be wartrained.
That might be a little bit hard to do.
didnt you say that goblins shoot nets that did that. cage-a-pult ideaa is scrapped now. replacing with paralyzing poison from stingers
Not the cages, but pets that do labor. No one in the entire modding community got that to work. (except fishing)
Beyond all of that, one question that should be answered: how many people would really use that feature? Just speaking for myself, I would rather have a non-slave unskilled laborer to have one less idler.
I had thought about a halfling/hobbit race, specialized in living above ground; then I came to MDF, and saw that the features I thought of we're covered by the dwarves (Brewery) and the kobolds (obvi). In the back of my mind, then, was the notion of a race specialized in unarmed combat: their anatomy would be such that they would rely on their wrestling/striking/biting/kicking skills to deal damage/incapacitate, with their 'weapons' basically being spurs that would utilize their unarmed skills, with a range of options covering the damage types; basically, a race that could make 'knuckle dusters' AND claws, etc.
The point is, you could do that with an insect-type race, whether they were wasps, ants, bees, buggers, Zerg, tyrannids, whatever. Combat-wise, that would be a pretty easy point of departure, modding wise.
