Papainfernape, you're arguing against the point without realising that your counterpoint is the same as Tea's, just coming from the opposite direction. "dry skin" on humans is exactly how the ability is supposed to play out; the bearer has skin that is permeable to water to some degree, and allows diffusion across the membrane. What's happening with some of the entries here is that they are interpreting Dry Skin as involving an integument that is completely waterproof, largely in the form of reptilian scales, the waterproof-ness of which is pretty much the trait that defines them from the amphibians, visually. Other than that some people aren't giving a clear enough indication/explanation as to how sunlight damages their entry.
