I envision these as some dark god deciding to replace goblins with something much, much more dangerous in order to wipe out all life. The entity raw is not changed very much-these are basically goblins with the size and damblock to match a bronze colossus and bodies made out of iron. If the iron bodies does not give them the ability to resist magma, then I will need to give them fire immunity as well. They drop masterwork iron statues when they die, as well as the equipment they were wearing.
I haven't managed to test them yet, so if you decide to try them out and encounter any bugs or have any suggestions, fire away. They're not TRAPAVOID, but you suck if you beat them using stacked cage traps!
