FFXIV Moonfire Faire Corner Post Shortcut Setup in Jump Puzzle Tower 

I finally found a consistent setup for the corner clipping skip in the jump puzzle. Basically you set up just a little offset from the corner on the post and then aim yourself exactly at the nearest corner of the platform. It's easiest to do with a top down view. After that, you have to press forward and jump in quick succession. The timing has to be just right. Press forward too soon and you just run off the post (happens once in this video). Press jump too soon and your jump won't be far enough.
