There would be specific types of minions one for mining one for crafting one for defending and one for attacking you get to pick its purpose it has half the speed of the normal character and you need to give it a tool. it has health and cogs and destroy it you will need to recall it back before the eruption. you can craft it by getting circuits from the basements of houses and the body parts of other robots.
A mining drone is planned, but some minions and pets have been heavily suggested. I’m merging this one due to how similar it is with another one, while this one provides more details.
