"The Ubel Route" is basically what you can visualize happening you can make happen, within the context of the power.

I would rather have Ubel's cutting-things-at-a-distance power, although its not specified in the anime whether that's all she can do without spells, but that's not in the OP. Now I think about it, the moment I'm jumping on clouds I'm learning draconic, so there.

Also, technically, clouds and fog are equally transitable; Saying they are the same thing isn't even a stretch, with the minor caveat that they often form in different ways.
