@Spirited I'm not even sure Neo and Weiss used Dust, as there was no runic symbols shown. So either they utilized low-level Dust sorcery, or some manner of aura barrier.

So with regards to Glynda, I've always assumed she specialized in purple Dust and is skilled in it enough to make it do whatever the hell she wants.

Besides the White Trailer, two of the four (Ice, and Lightning, no Fire and Wind yet) basic Dust appears to be tied to a specific stat. Ice Dust is tied to defense (Neo and Weiss using it is an example, additionally, that ice dome thingy she made), while Lightning Dust is tied to speed. (Weiss' hastega to Blake and herself.)

I'm gonna assume Fire Dust is tied to attack as well. It can explain Zwei's fireball attack though. Wind Dust is the odd one out.

These are all assumptions and personal opinions. Don't take my word for it.

@Bespectacled

That was pretty much the idea. Fictionland has nearly always ran on the idea that Runes = magic *ahem*, sorcery, rather.

Weiss has shown some potential in Glyph usage. But hers is a natural-born one, rather than through training with Dust. My point on Spirited above with regards to her usage of a Dust barrier may be a hint that she's not as skilled as Cinder or Glynda yet.
