* A round in D&D is actually 6 seconds (approximately) instead of 1 second, but this is for rule of cool. Still, 200ft/s (136~ mph, 200~ kph) is pretty damn fast.

I've actually hit maximum speed in a game session with -another party member riding on my back- ( sroecastle, sorry not sorry), this was in a short scene, after speaking with elves, I dove down from a flying ship to meet up with the rest of the party before we left for elsewhere. We all laughed at the gnoll's fuzzed up hair at the time but a more malicious DM would probably have asked for a fortitude save vs wind shear or something.

I'm no aeronautic engineer, I know, and I don't exactly have a wind tunnel to see where the transonic vapor cones will happen on a dragon, but I'd like some input on that.

I just feel productive this last month. Rest assured, commissions are ongoing, I just drew this between asking on corrections/redraws. I had fun listening to Ace Combat soundtracks for this.
