I am whole fully terrified of spiders so when I devised this commission I asked myself what would make a spider even more terrifying? Not be able to hurt it. Covered in a thick, metal carapace the only real way to hurt them is with extreme external force, i.e. a sledgehammer, or fire. For some divine reason the webbing they excrete is highly flammable so you can only imagine lighting a little on fire and watching it trail back to its owner like a fuse. Upon contact there will be a messy, somewhat dangerous explosion. The big one there is a queen, gifted with the ever so much creepier arms for better grabbings.
