After talking with one of my players, I realized that neither of us know what a "riding drake" is. Is it a species of drake/wyvern that has non-functional wings (like a Diablos or Basarios from Monster Hunter)? Or is it a large 4-legged and wingless lizard that we call a "drake" as a misnomer, like how sea horses aren't horses?
Are there any depictions in the text or adventure paths? I haven't been able to find art of it.
Drakes are the monkeys of dragons, they're quadrupeds with 'batwings' for hands/front legs. So it's either one with non-functional flaps or what happens if you strip a dragon of its wings
Ah, so they are related to other drakes. Then maybe a drake/wyvern that walks on it's front wings, like Tigrex or Nargacuga from Monster Hunter.
