The Five Elemental Phases focuses on the transitional nature of the target. Only the Windborne can harness this magic.

The Magic
Magic of the Elemental Phases is not about wielding the element, but transitioning a target using that element. For example, the Fire Phase does not wield flame, but rather could melt metal. Consider that the Windborne is the embodiment of that phase and can be the medium through which that phase can act.
