I think she has Dust in her dress, which would explain why it glows when she is fighting Glynda. As far as Dust and Dust, I don't think that the Elemental Dust is the cause of Semblance because Dust seems to be mostly based around forces of nature, but a Semblance can exist outside these things. Ruby for example is able to use speed, which isn't a force of nature. Same could be said of Blake's ability to make shadow clones of herself. This is why I suggested that Semblance may be the result of the original Dust.
