This skip was found by Maximillium. You need quite a bit of base movement speed to do this skip. My current base movement speed is 231%, although 220% is most likely enough.

The wallclip:

1. Stand close to the wall, but not right next to the wall.
2. Use Havoc Metamorphosis or Vengeance Infernal Strike through the wall, aimed down onto the floor of the pillar.
3. Move back out slightly, and double jump onto the ledge shown.
4. Carefully walk around to the right, make sure not to clip back onto inbounds.
5. Go past the wall, and triple jump up to the next layer. It's easiest if you start your first jump while holding the Back button.

The glide:

1. Face towards the crumbled part of the last platform.
2. Triple jump dash, and immediately activate Flexweave Underlay or a similar parachute effect.
3. Immediately dash again, and turn around without holding any movement keys.
4. Backflip and turn back towards the way you're moving.
5. Use Potion of Gusts to land on the last platform.
