So like a vaccum seal?

I don't know. But imagine if you could with some ability fix others spirit webs? The positive implications might be the ability to heal others trauma, but on the scarier side of things a lot of magic users have cracked spirit webs that allow them to bond with investiture and if you could heal those cracks you may inadvertently seal off their investiture access.

Windrunner Adhesion manipulates atmospheric pressure yeah? Or at least it simulates it or something since it's the surge of pressure and vaccum. What I can't figure out is which way Windrunners manipulate it make things stick together. Are they creating a vaccum seal effect by decreasing pressure or are they compressing air/increasing pressure to the point where the target people or objects cannot move away from one another? I think the vaccum sealing is more plausible considering Kaladin never gave Lopen the bends but either way a Windrunner could make things "stick" to one another.
