I managed to get this damage warp upward after using the black feather, heading towards the parachute power up.

Things to note is, this was done in the 1.074 & 1.075 patch.

And only doable on the 2nd grinder or saw..no idea what there called. Once you jump off the ledge you are hanging on. Pretty much what you see in the clip is exactly how it needs to be performed.

I tried to do it at the bottom, didn't work. And i tried doing it as i was hanging on the ledge with no go. Pretty cool for it being accidental, and pretty sure it saves time since your avoiding having to continue to jump up :D (I also tested for only 5mins just to check how it was done so if im wrong about something im sure you'll let me know)

Got a similar warp without damage, haven't been able to do it again
