Perhaps this is an issue of single shot guns still being the biggest banes of any fight to just about anyone, they screw over mages in particular, can kite effectively when paired with winged serpent, and they weren't all too effected by a recent change to power for guns, their massive utility carries their fights to the nth degree, but for the most part I don't think this calls for a buff to steel aura, Steel Aura is already very powerful and while I think it should apply to on hits and on crits applied from statuses, I don't think it should negate shell effects in their entirety, as it doesn't stop skills in general.

To summarize, I believe that perhaps Celcius shell, Sonic Shell and even null shell are too damn effective at what they do when paired with One Overcharge, which I believe One Overcharge should perhaps effect shell damage and not shell effects.
