I'm back, with another map
Demonweb is a wee bit trickier then most wilderness areas in that the webbed paths that you use to get from rock to rock can change each time you go inside, so don't be surprised if there's a path not shown here or a path that's shown here but not on your screen. Lots of ups and downs I can't show here too so keep that in mind.
Looks like rare encounters are random-ish, saw the same rare spawn in 2 different places (not in the same instance).
