If you learn a route by spending ten years in a Wilederness (type, depth doesn't matter) you can then reach it by traveling Wilderness to Wilderness at the bottom of the page.
Imo it is a good idea to do that first before starting to farm.

That is not what I meant. I can easily go to any wilderness manually. But when I am trying to grind out imprints the game needs to be able to automatically reincarnate and go to the wilderness I am farming. Which it can with a saved path.
But once I have gotten all 20 imprints there I want to switch the saved route. Its not hard to do that, but it is tedious to have to start a new run and save a new route. And you have to do this 45 times. Compare that to the mono wilderness where I just set the save route to the random destination and let it run until they were all done.
