A Dread Linnorm in Dungeons & Dragons is a colossal, two-headed dragon-like creature renowned for its destructive power and malevolence. These fearsome beings are characterized by their massive, serpentine bodies covered in scales that shift from black to gray as they age. Standing as one of the rarest and most dangerous of the linnorms, Dread Linnorms possess two distinct breath weapons: one head can unleash a cone of chilling wind, while the other emits a cloud of scorching hot dust.
