Could this mean Plateau Skip?

Oh, interesting.

I just realized that this can probably be used to jump off the tower on the plateau. It might has to be a heavy / 2-handed weapon, but I'm not sure.

In that case could it be done with the woodcutters axe conveniently placed on your way to the tower? I'll try it out soon. Unless someone else already has.

It has nothing to do with the weapon. Narcissa pulled out the paraglider for a few frames in the air which is why she didn't take damage.

So far we didn't find a reliable way to skip fall damage.

Also Plateau works different. Its not the fall damage that kills you. There is a void floor around the plateau that automatically kills Link as soon as he touches it and we didn't find a way around it (even tried riding a big rock off the plateau with stasis)
