I had to skirt the whole of level 19 and come in from the side. It's actually down a further half level from that. Possibly it didn't start out that way.

I'm not sure if you're coming from the other direction if there's a better route. It took quite a lot of scrambling and a bit of blasting. But, Bill. Don't blast anything if you can help it. I'm not sure some of these supports will stand any further concussions. You might be best to follow my path, after all.
