I wish there was a more concise way to phrase that question. I've asked it a couple times and always get some interesting answers.

This is inspired by all the "isekai" stories in anime and manga where a hero is summoned to help fight the demon king, along with the LitRPG genre. They use game-like interfaces to track stats and skills. Not just the typical combat ones like magic or weapons, but mundane skills like cooking, cleaning, walking, resting, drawing, lying, etc. Naturally, higher level skills tend to surpass basic physical limitations found on Earth. You could run faster than a train if your speed is high enough, or sculpt an exact replica of Michaelangelo's David in just a few days with a sculpting skill.

So imagine you got summoned to such a world and went through the whole "defeat the demon king" quest, and could choose one skill to take back to Earth. This includes anything from some specific magic ability like weather control and invisibility, to trained skills like archery and blacksmithing, to even basic stats like strength and stealth. Anything is fair game, but you can pick only one.

So, what skill would you choose and why?

Stories involving dragons tend to be in medieval periods so maybe we can try to extrapolate forward in time a bit. Dragons could be from any mythologies or fictions of your fancy!

For my take, a dragon is a flying fire-breathing giant lizard with the size and toughness of a big building. I believe a critical factor is how tamable dragons are. If not at all, they'd go from something humans fear and run away from, then being hunted for glory and materials, then being protected in conservation areas to prevent going extinct. If they can be fully domesticated (like dogs), they could expedite for warfare, transportation and industrialized metalwork. The most interesting scenario imo is the in-between where they could only be partially trained. Maybe a skilled trainer can get them to behave 80% of the time but there's a low but significant chance that they get agitated and wreck havoc. How do we make use of them while ensuring safety and intervenability?

On the cultural side, we might not have as many myths and legends about dragons anymore. We might find the idea of giant flying fire creatures utterly mundane (phoenixes might be less interesting by relation even if they still don't exist in this universe). What would we mythologize about instead?
