There's two new skips in the vocational block chapter, both are done the same way.

The first one is done as the Groom is chasing you, so it's risky and there's basically no room for error. It saves about 30 seconds. If you manage to do it, you need to save and quit after you get down so you can do the next skip, since otherwise the elevator will block you from dropping another floor.

Here's the next skip

As you see it's pretty much the same, except now you can do it without someone trying to kill you OpieOP .

Here's a setup I found that works well to get the drop

That is for the second skip. You need to hug the edge and inch yourself right until the camera moves forward. Then just turn and look a little right from the corner and walk backwards. If you did it right you land on the floor below.

The setup works similarly for the first skip, except you look left of the corner.
