While in a Dungeon and you are stuck behind a gate that u have to destroy or was just a little to late on getting to a certain area. If you go to a gate you can hit and target the gate and go to either the left or right side and use blade scud you will go right through the gate.
Post and let me know if you were able to do it. I have done this in the newest NA update. It might only work in eod or gate similar to eod. I tried in ic1 and it doesn't work. Maybe i just didn't do it right.
