[quote]That's assuming that just because Gren lacks most of his original body, his aura is suppose to be weaker. This isn't Star Wars where cybernetics are inherently conflicting with mechanical parts or even armor. Besides that most of his aura already goes into making the machine work anyways, and that isn't limited to just allowing him to move. It effectively pumps his aura throughout his entire body like a mechanical heart, precisely so he doesn't need to constantly focus on pumping his spiritual blood all the time. With the benefit of doing what aura is suppose to do anyways, like protecting its person.[/quote]

Not weaker, simply not evenly distributed. The aura should emanate from his body, when you lose a limb the limb does not keep generating aura, it is dead. Whatever aura existed in the limb now exists in the rest of the body just with less surface to cover. So Gren's entire aura is concentrated in what little organic tissue his has left, which I believe is his brain and a handful of vital organs. Now the aura can be extended outside of the natural body, channeled through weapons to increase their durability, pack a bigger punch and so forth. Doing so should dilute the aura the further it gets from the source. So Gren would be capable of pumping his aura out from his organic tissue to the exterior of his mechanized body but doing so would require a conscious effort and create a weaker field compared to those generating it on the surface of their skin.

[quote]Gren's aura is constantly active for both protecting him and allowing him to live much like Sapphire is constantly breathing. Because as discussed before, Gren's aura is what is powering his body (since we also nixed the idea of alternative energies like dust or fusion cores). We also had mentioned that while EMPs are effective against Gren, it's not instantly lethal, only that it shuts down a vast majority of his functions beyond what's keeping him alive. I.e. Moving at all.[/quote]

And taking the wrong lesson from the conclusion to a discussion. What we nixed was the potential for Gren's power source to be either radioactive or explosive. It could still be an alternative clean power source, it doesn't have to be aura. The EMPs could easily only shut down his superficial functions because his core cybernetics are shielded. A simple explanation for his limbs and such not being shielded is that it would make him unreasonably unwieldy for the task his upgrades were made to perform.

[quote]The idea that he's constantly struggling to make his heart use his aura to just keep him alive is frankly kinda ridiculous,[/quote]
Not what I said in the least.

[quote]...not to mention making him much more of a liability If he can't rely on his aura to serve a basic function everyone can do.[/quote] 

His aura being less reliable is essentially why he has a boatload of other talents, stop gaps and redundancy to fall back on which everyone else doesn't.

[quote]If you want to nerf him that badly, I'm willing to satisfy that desire by limiting his semblance instead, shortening its range and adding more caveats to avoid being affected by it.[/quote]

I'm listening but I think the aura is better thing to nerf as all of his physical upgrades are made to increase his durability, and strength, nerfing his (let's face it) magical abilities that contribute to that is the perfect counter balance.
