The prompt said
If you could choose to be a master (or mistress) of any skill in the world, which skill would you pick?
I choose Dragon Taming.
Dragon Taming would be akin to one of those wishes for more wishes. It is a single skill which could encompass many required skils, eg: Winter’s Grasp, Shimmering Shield and a high Survival skill. Attributes such as high Intelligence or Willpower would be par for the course.
With these skills in place as well as a trained High Dragon, it would be hard to defeat me if I choose to ravage the world.
Outside of the world of role playing games though, I would not be much good. The closest thing the real world has to dragons is a monitor lizard. I doubt I would do much more than provide a rodent removal service.
