Two areas I can't fully explore

[Ixmo]

Hey all. Hoping someone can help me in exploring the two zones below. I've covered most of the map now but these two areas seem to elude me, maybe I'm missing something obvious but how how can I fully explore them and get the items?

Land of Origin

Upper Stratum - Administrative District
https://steamcommunity.com/sharedfiles/filedetails/?id=3414389293

In the Upper Stratum area the wall is slanted so can't go straight up and to the left is a waterfall so I can't grip onto the wall.

Thanks for any help!

For Land of Origin it’s a bit of a tricky jump challenge, you have to get around each spike in the ceiling and grab onto the straight wall on the right side and repeat until you’re at the end of the room. Using Number 7’s second skill should help with that.

For Upper Stratum can’t you just Garm’s Ascent while standing on the floor at the right side of the room and then dash into the top right corner?

Land of origin
Cling to the hanging walls, they're straight vertical on one side

Upper stratum
Either highjump, slam into the ceiling and then proceed right, or get to the top of the waterfall and then jump-combo-dash your way to the platform (what I did)

Thanks all. Was able to finally reach both items
