I read the copies as not caring about consequences to themselves because they'll be going bye bye anyway, this is potentially massive consequences for Original Joe and the world. Hopefully it will never actually matter but if it does then this is a massive idiot ball moment.
"Unlimited logarithmic scaling" means heavy, compounding diminishing returns. It'll keep falling off at the same rate per-effort even as the returns per-effort decline. It's a big boost that stacks with the existing boosts and will get even stronger, but it won't spiral out of control.
March's tripwire before was pretty simple, if accidental. The trader's brain-bomb was set to go off automatically if he didn't follow an order exactly when he was supposed to. March's timing power let her give only orders that could be obeyed, so there was no chance of the bomb going off due to incompetence, only to rebellion. Or to some undetectable actor getting in the way.
If you aren't using fractions of a planet, it's not beyond description. If you are using fractions of a planet, you should only be firing at targets above the horizon or at steep downward angles.
Keep in mind, Joe needed to get the knowledge of a soul manipulation power before he was able to unlock Chen's Aura, so I'm betting that there's a lot more to spreading it than just saying the words.
I think I recall Joe commenting on how his sword-gun-thing from field repairing Leet's tech had an absurd range if used with large blade version was used with runes and Energize.
A Lagrange point:
he didn't, sting blew it all up & away
That's fairly far then. So many people would faint in fear if they heard Joe think out loud, "Okay, so my three day old outdated version of my even more outdated superblade that once cut the sky can reach somewhere in the Earth's orbit I think. I wonder how far my current one can reach..."
This is kind of nice. To be honest I'm personally the pragmatic/utilitarian type that is perfectly fine with just killing off the types of villains that are either irredeemable or nigh uncontainable and found the strict katsujinken philosophy in HSDK kind of annoying at times, but it's nice for Joe to have something like that amidst all the other horrors in the Forge. Like that soul shit he just got in this chapter. Or the summoning almost literally Satan stuff from before, or any of the other couple dozen S-Class extinction type events bumping around in his noggin. At least something in there cares.
He should be pissed at March though since she's the one who hurt them.
