Robin will have only enough time for a glimpse before the crack closes again - but it's likely perfectly obvious even without the Analysis what this person's typings are. His keen eye will see that the flames surrounding her body sputter and flare as if contacting water - which indeed they are - and a strange vapor is rising simultaneously from her body.

There is nothing about her appearance that readily suggests her innate ability: her frame is frail, obviously sickly; she's hardly ready for battle. That she possesses the traits of a God of War is exceedingly unlikely, but her actions suggest some control over a third typing - rock or ground. In the absence of that possibility, then, it is safe to conclude that this woman's control over ground is her Enlightened trait. Ergo, she is a Child of the Shifting Earth.
