Xayah ult

So thanks riot for this. So for those of you who don't know, xayah' ult makes her jump up into the air for a little bit and then throw a bunch of feather down. Now for whatever reason this ult (where she is literally in the air) doesn't allow her to go over walls. But shit like sejuani s's Q and tryndamere's E can somehow phase their bodies through solid rock
