Huh. So it's possible that it's only possible with extreme delicacy and precision -- and, probably, if you are working with settled magic, i.e. magic that is inside items. Trying to use Winds externally, one Wind on another Wind, might not get you anywhere; you can't pull off the delicate touch involved, because to gather any amount of this second Wind, you have to be more direct and employ more contact.What little you do know suggests that it uses items that have other Winds inside them and very carefully manipulates them with very light touches of Chamon. If done properly, no two Winds ever directly touch at any point in the process.
Well I mean, not necessarily a shot in the arm.Regardless it's something of a shot in the arm for trying out wind-wind manipulation. Granted it's not going to be simple but I think it's worth the experimentation. We're in the best place of all human wizards that have lived so far to be able to try it being immune to dhar corruption and having a magical null clean room which is the best synthesis of dwarf and college techniques that currently exist.
Because keep in mind the other thing that BoneyM has said about the Winds:
It's possible that the only way for a human to have hypothetically become a High Magic user, would be if he extremely absurdly carefully mastered 1 Wind of Magic without getting any Arcane Marks at all, and then continued to do that for the rest of the 7 Winds. And then somehow combined all that. All without ever getting an Arcane Mark. He'd somehow need to live long enough to do that, too.You can study multiple Winds one at a time as long as you have a good long detox period in between, but as soon as you get an Arcane Mark you're locked into whatever the Wind you got it for was, so most don't want to risk getting stuck with a Wind that isn't the one they're most compatible with.
It could be that any Wizard who gets an Arcane Mark for their wind -- like Mathilde with her shadow and flickering candles -- is screwed out of this hypothetical.
