It is actually, even on Ruby's profile its noted that she took hits from Tyrian (why it says he was casual I have no idea though), and it is in fact accepted, theres even an entire list of instances of this happening on our Powers and Abiliities page for Aura (RWBY)
But why isn't it specified as 8-A? Like, shouldn't she be High 8-C normally, 8-A to Low 7-B with Aura? Though, if the 8-A part is accepted, then I'm gonna remove the restriction on his buffs. Dude can now buff his strength up to 7 times, so he'll be >>>7 times stronger. Also, the profile doesn't suggest it was written in a way that they can actually tank 8-A attacks, as even the profile states that it can tanks from those comparable to them, and the dude tanking feats is either A:
An outlier
or B, just a casual punch. As the profile suggests. And besides, it just says Higher, not 8-A, so I don't see a reason why we should assume its valid until a CRT is made.
As for why I didn't just make him 8-B... I don't know, tbh. I kinda forgot that exists, but this feat happened in the end of Floor 5, and Yoon-seok found it utterly useless and just threw it away.
A scan for which? And RWBY characters in general are more akin to dodging attacks rather than blocking them when possible, taking hits is much more detrimental than avoiding them as every hit they take will gradually drain their aura, unless its someone like Yang who actively gets stronger by taking hits.
I mean, it's a slap, and I doubt she will be able to dodge it, tbh. Also, a scan of her blitzing people that blitz her. And he manages to catch people who are comparable to him with this attack, too.
I mean, Ruby scales well above the 7 ton feat (said attack was done by a casual attack from weiss, specifically a single fireball out of cluster of them, with the cluster itself being a casual attack), though if he scales well above 10 tons why wouldnt he just be straight up 8-B? If the chain supports it he would be justified for that. Aside from that though, Ruby's bullets can already rip opponents comparable to herself in power in half (piercing damage ftw) and her elemental bullets are stronger than her normal ones on top of having elemental AoEs (fire dust explodes and sets opponents on fire, ice dust encases everything in a multi-meter radius in ice that 8-As struggle to break out of without a heat source, lightning dust explodes into homing chain lightning that causes paralysis, and gravity dust is significantly stronger and can kill opponents as strong as Ruby just from the shockwave of the bullet passing them). Flight and forcefields are both things Ruby has herself as well as has experience fighting against.
She only has psuedo-flight, rather than straight up full-fledge flight like Yoon-seok. Aside from that, the literal energy that coats Yoon-seok is similar to that, as his own attacks cannot pierce it, as shown in the justification of the ability.
Also, I don't see why he can't just... dodge with counterattack, or flight. And if it becomes way too dangerous, he already has an ability that lets him absorbs all the attacks and send it back to her, and if that fails too for some reason, he also has another safe-move that if he is in a near-death situation, he becomes invulnerable to that attack. He already resists Electricity manip, and his danger sense and instinctive reaction should be more than enough to dodge all of that. Also, doesn't she run out of bullets?
Oh boy, I can grab the scaling chain if youd like, because ruby is stupidly skilled. Why would standing in one spot and pulling the trigger of her rifle exhaust her...? And what is his stamina like?
I've seen it already, and a lot of it doesn't seem that impressive (And the Aura part iirc is just outright bs). As for the stamina part, I'm talking more in-general, like eventually sleep and hunger are gonna get to her. And the more the fight goes on, the more skilled, faster, and stronger Yoon-seok gets. Yoon-seok also has Analytical prediction, and resistance to it, and the literal first time he got a sword he managed to defeat, and copy a dude's martial arts which are composed of multiple martial arts. He can fight completely on instinct as well.
All of this is in his 9-B key, his High 8-C key is way more stronger and skilled.
As for his stamina... well, dude can train for 8 days straight without feeling an ounce of hunger, thirst, or sleep. And fought repeatedly for many hours against a dude that can violently destroy his head with a single punch, and he can't even do a single cut to him, and that was in his way, way weaker self, and had a specific weakness. He has now gone on for like, half a year without being tired, with the only instances of him being tired is against dudes who are much more superior to him in everything and him having to use everything in his arsenal, and EVEN THEN, his stamina gets constantly replenished, and never hindered his fights by much.
