But, yes. I know. I meant that she was deleted when I previously uploaded her, before she was uploaded for approval. As per the edits, Janus suggested that it may have simply been a glitch. Which, if something was happening around the time that someone was tinkering with the site, is completely understandable.
It isn't so much Auto hitting, as it is firing a homing missile (Using missiles in the form of a projectile weapon. It simply seeks out it's target and ensnares them, doing no damage whatsoever, and if the target can figure out that chains rapidly approaching them is a bad thing, they would render it effectively useless by outrunning it (something which has been shown to be possible. The only case where I would consider it auto-hitting is if they were literally right on top of Aqua when he set his Anchor Point and got marked there and then. But, even then. If you're literally sitting on the barrel of a shotgun, you can't really call someone a modder for just bulling the trigger and blowing your prostate into your brain now, can you? (Enjoy that lovely graphic, by the way)
I have also been toying with the idea of keeping the length/durability spread out across ALL chains. So if there's 4 chains, each 50 Feet long, each one would only have to pull against it as if it were a 200 foot chain. Though, once one break free, the others would be left with the strength of the remainder.
As per their Aura Constructs, the Summons and Clones are rather unique, as Weiss' are for direct combat purposes. Wukong and Blake (though they both vanish upon being struck or, in Blake's case, activate a Dust effect.) both use theirs for distraction and/or evasion.
Aqua uses his for neither, simply to restrict movement. Natural/fixed terrain, such as floors and trees, walls and doors and the like, would pose a barrier, but something like an Ice Wall erected with Dust would be ignored.
There's also a time limit on it, of five minutes, with the chains getting weaker by the minute. After 5 minutes (or once they break free), the chain completely vanishes, requiring Aqua to re-mark his target and reactivate the chains.
As per Aura, it isn't perfect. In the show, we see people with their Aura active feel pain, and even take physical damage. Jaune, for example, takes a few punches from Cardin which leaves him with a black eye. He then later looks at his Aura reading and it shows he's taken a significant Aura loss, BUT he still has his aura. Unless you wish to hypothesise that the bright flash of light was his Semblance, and it chunks him 20% (give or take) of his Aura to use it once (which the writers have confirmed, that was NOT his Semblance) then it would stand to reason that Aura is not a perfect defence and can, with great force, be overcome without breaking it down first.
Further, though less extreme proof of this, is how people are being knocked around and feeling pain. Pyrrha, for example, makes several pained gasps when she takes blows from Cinder. Jaune from Cardin, Cardin from when he punched Jaune in the face, (we see him shaking his hand like he seriously hurt something), Ren when Nucklave bitch slaps him into a wall, Jaune when he takes several stones to the face and groin (possibly out of place comedic relief, but still another example) Yang and Mercury during their 1v1. They moth make hisses and grunts of pain (even before Yang smashes his Aura to bits). Ruby, when she falls into Roman's operation and is KO'ed for a short while. The list goes on and on, but I think you get the picture. If he punches something hard enough, something that doesn't yield... Newton's Third Law takes place. For every action, there is an equal reaction. (and before you say there isn't that much realism in RWBY... Nora's Grenade Jump proves otherwise. Other examples, I'm sure, but that's the most memorable. Just cutting this one off at the pass. Too many in the fandom decide that RWBY isn't set on Earth, in our universe, so Basic, Fundamental Physics don't apply.)
The chewing through his lips and tongue is still a valid concern, however Aura does not protect the body 24/7. It may provide cover overall after being unlocked, but Pyrrha and Ozpin both state that it must be activated in order to be of any serious use. Pyrrha, just before unlocking Jaune's Aura. And Ozpin, when Oscar complains about his Aura not automatically protecting him. It seems to function like muscle. An experienced fighter will know exactly where and when to tense and relax to minimise damage from punches, but if you're just chilling in your room, absently staring at the ceiling, you're not exactly anticipating someone stabbing you in the cheek.Though the healing effect of Aura would, no doubt, slowly get to work healing him, but he'd have to register the cut itself to send his Aura there, like flexing a specific muscle. It's not the best analogy, but it's the closest I could find that fits how the show has (barely) explained Aura.
The only up-side to Analgesia is a double sided sword. He can't feel pain. Yeah, it's great for a tank. He could stand there all day and not feel a thing. Except maybe a little bored, then wet when he starts bleeding.
Unless he's got a sword sticking in him that he hasn't noticed yet and doesn't realise that he probably needs to back off and get help. Or if he's just gone and broken his wrist because he punched too hard, or because he was pushed and tripped.
The only other "strength" he has is his upper body and lower back strength from carrying a shield that is 6"6 tall, 5" wide and four inches thick. Not sure exactly how heavy that would be. Would have to do research on military grade metal, their weight per volume, then figure it all out. Purely because I want "Whosoever holds this shield, if he be worthy, shall possess the power of Aqua." written on it, then pull a Thor and just drop it on someone and walk off. xD
