Frill-Necks are Waste Devils so called because of the large ruff of skin which usually lies folded back against their heads and necks. The neck frill is supported by long spines of cartilage which are connected to the jaw bones. When frightened, a Frill-Neck gapes its mouth, exposing a bright pink or yellow lining and the frill flares out, displaying bright orange and red scales. This reaction is often used to discourage predators or during courtship.
Frill-Necks are capable of leaping large distances as if they were nothing and by shaking their frills while screaming, they can summon up dust storms up to fifty feet away from them. This is often used to blind potential threats and prey. Their tongues are also very sticky and durable, allowing them to bring creatures in close to maul.
Like other waste devils, Frill-Necks speak a broken form of Draconic and while not unintelligible it fails to express more complex concepts.
