"When I had just turned, the edge of whatever transmutation I made was one and the same as the edge of the transmutation area - to get fiddly little details I had to fiddle with the shape of the transmutation area itself. Now, I can just make them in whatever shape I want, as long as it's in the transmutation area. This actually makes it significantly easier to have distance, because before it would always have a little trail of whatever it is I was making leading back to my anchor. I could put it back, but now I don't need to waste my time changing it and putting it back at all. Though it's faster to let the transmutation area be my border if I can."
