|In 2nd edition D&D, the ferret keeps you as a pet|
It's 3 feet long and weighs 500 pounds. Let me put this in scope - a pomeranian of this density would weigh the same as an average adult American female. Their primary diet is gold, and they scratch with their sharp claws - all very similar to the aurumvorax.
This walking pile of loot is most famous for its death. It can be turned into a golden fur coat that's roughly as protective as Field Plate, and the rest of its body can be melted into a paltry stack of ten thousand gold pieces. By comparison, that's significantly more treasure than a dragon of the same XP value. Not bad for a mutant ferret.
As a teenager, I wondered why the game designer would encourage players to kill a fur-coat wearing gold-digger laden with riches. Don't worry though, I figured it out when I was older.
