So my friend had this question about the unique abilities. She said, "If I was a wind glass, can I have illusion powers?" I told her no, only mirrors can do that but she then said that "illusions can be created from air densities distorting the sun's rays." So that made me think, can it work that way?
When I started making unique abilities, my general idea was to think elemental bending from Avatar the last Airbender and think “what could someone with this kind of abilities specialize in?” And then general things that are associated with the elements. Like, cloud = air/wind (even tho it’s made of water. I associate clouds with air)
You can get extremely technical with this and sure, I suppose a wind Glass could do that. But it would no way be as strong as Mirror’s illusions are and only work when there’s natural sunlight (since a Wind Glass can’t create light. Tho they could team up with a Fire Glass)
