Watching Idun draw a lot of it. Actually, I must have liked it beforehand, but I wasn't really aware of it before or so. Well, I liked regular transformation, and immobility from expansions... it's got some similar traits to those, but it puts you in a much easier state to be moved around, so with less mobility you might get more action you aren't in control of? Or not, if you're left alone! But it's still neat, I think.
