Presumely you need to manipulate all eight winds to make "Qhaysh" type enchantment, having all eight winds. Windherded if we spend a lot of energy on it, might be able to accomplish something like that, but well. AP Hell and all that
Remember that the elves consider Qhaysh to be the result of using two or more Winds harmoniously together.
You don't need to weave all eight of them together for it to count as High Magic. The techniques to use more than one at once all count as that, whether you're using two, three, or all eight.
The Cathyans consider High Magic to require all eight Winds, but the elves don't.
