The Shardspire plug in housing gives you access to a challenge, where you jump up a big rock spire to get some rewards. I don't know about anyone else, but I find the first part of that challenge, with the big rock and the spiky rock, to be the hardest part of it by far. Fortunately, there's a way to skip to a jump away from the end. Place the Shardspire challenge on your right long plug, and use a tornado fabkit (forget the name) to place the Ride The Storm challenge in the upper right small plug. Then you can activate the Shardspire, run into the tornado, and be whooshed up two thirds of the way up the spire, with plenty of time to steer back in, land on a rock, and not run out the Out Of Range timer. It's a little tricky, but it's a hell of a lot easier than running the Spire normally.
