Are Anti Starship Arachnids immune to Dyson gattlings?
The dyson sphere in my game has done a wonderful job cleaning up a few planets. However, it seems that the AI has figured out that dysons cannot damage arachnids as there is now a planet full of 500+ arachnids and only arachnids to fight off the dyson gatlings. It seems that gatlings don't even shoot at them, indicating some sort of immunity. Is this intentional? I don't see any sort of listed 'gatling' immunity in the arachnid description.
I can include save if required.
