Rafkan Thrasher.

Rafkan Thrashers effortlessly glide around caves as if swimming through some unseen aether. Despite seeming to float around weightlessly, Thrashers are as heavy as a fork-lift manned by a drunk one-eyed oaf, and they are just as dangerous. Beware that Thrashers are capable of propelling themselves at startling speeds as they attempt to impale their victim on their sharp beaks.
