This is a very nice and simple low level complication, with so many ways of it being overcome you don't have to worry too much about whether your players are carrying a grappling hook or not. At higher levels it tends to lose its usefulness when magic-solves-everything kicks in. I think it lacks an added layer of challenge though. I'll post some ideas on the scroll.
Additional complications to increase difficulty and/or lethality without too much effort on the builder's part:
A very good and complete writeup of an uncommon piece of equipment. Does the Kellerhadrin Plant fiber ever wear out or degrade? I'm sure the suits are broken far before then, but it seems a releveant qestion. If the plants are still alive when they are used you might even have to water your armor.
Ohemgee these are so adorable. I am tickled pink by Tauric's idea of them existing in more than one plane, and being large majestic bovine in one and tiny little nusiances in another. You obviously put a lot of thought into these sweet creatures and have a very clear idea of their abilities. Unfortunately aside from flavor I don't see them being involved in anything quest-related or grand. That's okay though, they fulfill their role very well.
