Colossal Frostbite Spider

Colossal Frostbite Spiders are a massive, and extremely dangerous breed of Giant Frostbite Spider. Standing at least ten meters tall, although rare they are most commonly found in caves. Like all other Giant Frostbite Spiders they do not live together, but are often accompanied by several minor Frostbite Spiders. They spit a highly corrosive cone of acid, able to dissolve almost any metal and even flesh. Upon attacking, they will make a screeching or scuttling noise. They attack with their mandibles and legs.
