Timber Jack's are known as the fastest of dragons.

These pillars are used not only to strengthen the dragon's wings, but also to sharpen the blade along it. A rider can also learn how to properly ride the dragon in order to maximize it's speed for the impact and minimize the chances of falling off during the strike.
