Soo the Other Thing i was talking about is in the Cynthia Fight It's not as Hard to pull off as Mushna Slope Glitch, and is definitely more of a silly thing than a game Break.
Still here's how to do it
Soo Fisrt wait for her to do an overhead slam (The one she's doing on the image)
Then just time it You Want To Jump As She is Hitting The Ground (Or close to that keep in mind that it is quite precise prolly like 2~5 frames time window Also Bringing the frame limit down to 15 makes the timing a lot easier although it can still be achieved even on 200 frames )That attack will normally just make you jump automatically but if timed correctly you should Get the same boost as if you were jumping on a
Then If you're ready for it you can try and use that boost to possibly stall on one of the arena walls
Possible solution
Just make the walls slopped and i would say put a ceiling just to be sure.
But yeah that's it for now everybody.
