Fed Upon by the Weirdling Beast -- but it won't end

[Deinos]

So I'm at Fed Upon (-78 or so). My temporal warden got hit by it by the Weirdling Beast, and now I can't seem to make it stop. Shatter Affliction won't work. I went up the stairs while fighting it, I guess that was a bad move, but now I can't un-screw myself. What do?
