I hope they do a quest chain for any nidhogg type enemy. Nothing to difficult to unlock, but some serious story and background, then the final quest is something like a leve that you fight in the open, (there are some pretty big open areas that would make perfect areas for some epic battles), and make the leve hard as fuck, but not glitchy and dumb.

Also rather than make it an hour running around in some lame dungeon make the battle itself the time sink. So 30min-hour long battle.

ALSO, let us cut off its tail, break its wings so it can't fly, break its claws, and break its fangs. Then let actual materials drop: fangs, wings, claws, tail... THEN let us make gear out of it all that we can HQ attach materia and convert into really awesome materia.
