Still havent tested it but if you store your position with the lean teleport glitch above ground, so like on top of a building. Then used the item glitch to climb over walls if you then activated the teleport glitch right before you hit the ground would you begin to move vertically which would make for a safe landing
Edit: Well it appears not to work
I think I understand. So for example, lets say you're indoors (like the long path to find Kellog) and you want to do an clip, but the landing spot is too far below and would kill you upon impact. All you would have to do is scope in around a corner, do the clip, and then teleport right before you hit the ground. If timed correctly, the ceiling of the area you're clipping into would stop the teleport and allow for a soft fall.
