[i]Well, the thing is Xuno is kinda dense[/i]. So gravity it going to win to some extent against a 400 pound ballistic green brick. So she'll be taking option D: All of the above. Huge column of water from the river, wind, shotgun-recoil, and pelting boulders at herself so she can smash them to try and slow down. Plus with a bit of luck, she can then use her ability to guide the falling rock-fragments to hit any monsters on the way down.

Granted, all of that is going to end up crashing down around Hasuno and Xuno is going to be all wholesome smiles after putting a crater into the riverbed. To her that would be a soft landing, she [i]could[/i] land softer but doesn't see the point since it already won't hurt her. She's basically a tank, which can be downright frightening if she'd actually get angry [i]and[/i] used her abilities to essentially be the tanky girl she is inside an adaptive stone power-armor, with a shotgun.

[hr]Didani [i]could[/i] try using her rocket-launcher as a jetpack, since heated air, confined and forced out the other end is essentially a jet engine. But as that's not a landing-strategy she'd practiced before, it won't be a reliable solution. I have... a few ideas, one is the tried and true landing strategy that'd work even if she had no abilities or rocket-launcher. It'd hurt, but she'd live; which tracks with her approach to brute-force her way to a simplistic solution. Otherwise I could have her play in the shadows once she punches through the tree-canopy and teleport to the ground with zero/mirrored inertia. Since that's a pretty staple ability of hers and she's probably been thinking with portals for quite awhile.

Which means she'd going to find the insectdragon's ability to meld/teleport through shadows equally annoying.
