aaaaagh

Echo Bazaar people: I am stuck, stuck, stuck in the Labyrinth of Tigers. I've been trying to advance my "Making Progress ..." quality to 14 so that I can move along to Coil 4, but I simply cannot figure out what I have to do to make it bump up from 13 to 14. I've tried EVERYTHING I can think of, but all I'm doing is racking up lots and lots of glim feeding the fish *g*. Can someone give me a teensy tiny hint, perhaps regarding which challenge is involved, or in what way I have to think outside the box in order to get it to happen? (Unless I'm either overlooking something obvious, or need one of my scores higher than it is. I hope this isn't something I need Persuasive for, because if so, I'm doomed. It's my worst score by far.)
