Royal Basilisk

The royal basilisk is aptly named, not for only the metal crown upon its head but also for the unique potency of its poison. The creature's poison manifests as a sort of cloying vapor that sticks onto and eats away at anything it touches. Their mastery of poison does appear to come at a cost, as the royal basilisk has no ability to petrify its prey. Although the royal basilisk can painstakingly shape a crown, some made of simple iron and others of rare skymetals, they much prefer to collect crowns crafted by other creatures.
