Catoblepas

A catoblepas was a seeming mix of buffalo, dinosaur, warthog, and hippopotamus that lived in swamps or wastelands. Legends said that hags raised catoblepases like cattle and fed on their milk.

Its most feared ability was its deadly gaze.

The flavorful death cheese sold by Aurora's Whole Realms Catalogue was made by using catoblepas milk gathered by blind monks.
