1) so she does have the speed with magic its only without. seeing that her stamina is around average human whoever would her magic capacity be in the realm of going for long periods of time or handle well when damaged?
When I said stamina, I used that as a analog for a manapool, hence the quotations. Her mana is enough to let her fight for prolong periods and fire countless attacks.
Stamina wise tho, she can take some heavy wounds and fight awhile before going down. Like it isn't insane but she can take things akin to being stabbed a bunch and keep fighting.
2) Yuta could try to move around via hypermobility and maybe analyical prediction if magic in frieren gives an aura (not sure if the series does that). Alongside his dura advantage and Regen he has damage reduction, instinctive action etc to help defensively and Rika could help block aswell
No he can't. As I said, she can control the trajectory of her attacks, every attack, the attacks multiple times faster than him, that she's spamming. Dozens at a given time, from all directions.
If he dodges, which tbh he really wouldn't be that capable of given the speed gap, he's just gonna get slammed by five more from the other directions, all while the beam he dodged just pivots and hits him anyway.
His dura advantage is negligible, and if Fern damage boosts, her attacks can one shot things that can otherwise invalidate her attacks completely.
Instinctive action and Rika won't stop danmaku, Rika can maybe block one or two, but she isn't firing only one or two
She can keep this up for a very long time.
And IA is pointless, dodging without thinking still means you have to dodge, which doesn't help when there's hundreds of attacks coming from all over that eclipse you in speed.
3) Cursed speech manip is sound manip so not sure on how curse res helps, given that additionally sorcerers as a basic resistance have resistance to curse manip
Because it's also curse manip? The part that's actually an issue is the cursed aspect of it, not the sound aspect of it.
4) Sorcerers additionally can amp their attacks via yapping about their abilities, Rage Power and Empowerment, Blackflash and Domain (if he lands) and the rika beam does apparently go into 6-7 kilotons of tnt so that'll hurt
Fern can survive that, it'd blow her shield out completely, but she could in fact survive that at least once directly, it'd just take a shit ton of her mana.
But like, all that stuff you mentioned, is only 7kt, that is his absolute peak. It's close, but that is
not one shot lv, and when Fern can create forcefields, she's gonna be able to block it at least once.
Buuut.... That's assuming it's even gonna hit her, it won't, she outranges so badly and is entirely in character for her to exploit that, that it just becomes Fern shooting a target from above the clouds or something.
5) Yuta does have some more abilities that can help such as sky manip, Dhruv shikigamis, future sight, etc. though future sight is if yuta gets close so its likely hard to get in
None of those help, Fern's basic attack method is like 100x his range. If she decides to fly away while danmakuing, which she will, not only will Yuta not even be able to follow her because he's busy dealing with countless beams preventing him from keeping up, but he can't actually fly nor does he have the range to attack her back once she gets out of range which wont even take a second on her end.
