Curiously enough there's almost no vids of Ryza 3, all I recall finding were some typical vids of mooks attacking for a bit and nothing more, but not bosses or status effects or anything.
That said there are a couple from the older games:

On another note, anyone has checked SAO Variant Showdown? I wanted to try it myself but it's not available in my country. There are animations, but are seemingly pretty hard to come across, though I did find an enemy that can stun:
The game looks pretty good at least in presentation.
Another one that I found by accident is Stella Fantasy, which honestly seemed pretty meh in just every aspect. I mean, everything is literally an anime cliché, the main trio are the quirky gentle princess, the airheaded big breasted girl and tsundere, the MC is a isekai'd Kirito knockoff, etc, etc. But despite that, the designs are cute despite being uninspired and the animations are pretty nice.

I had a couple of more animations, but as I mentioned, since they were on Twitch the vids were taken down after a while.
Two bad news here. All I could find was on twitch, so it will get removed sooner than later. And second, the game is a NFT one, so yeah, if you want to try it you'll have to get crypto stuff on your phone or whatever.
