Did you take the weaver’s tree node that prevents raising corruption? That was an issue some people had recently.
There isn’t a shade in “every echo”, you have to enter the “blue pyramid” looking node and kill the shade.
I think he might have meant timeline.
Yeah, I would have thought that too if not for this statement “do i have to keep killilng hte same shadeover and over and over int eh same echo to increase the corruption?” in his post which tells me that he’s doing the same timeline, just different echoes within that timeline.
