yeah, i can agree with this, i forgot that box was portrayed to be of special making, there could be more gimmicks to it than i thought, it may not be because of the attack cuz he took a punch earlier and nothing happened, maybe his magnetism gets weak if there's obstacles between kid an the...
looking back at 1008 it could be a special box that needs specific requirement to work, big mom's punch did nothing but this thunder attack did
or it can be like you said kid's influence over it got weakened because he's indoors now maybe the walls had something to do with that
DF just works, they don't need focus, still it require some thinking and training to get used to once the user achieved that it just becomes muscle memory, take cracker for example he just creates a strong looking soldiers with just a clap giving them strong haki and unlimited stamina...
kid doesn't strike me like the type who'll maintain constant focus on stuff, his arm and punk rotten seems like they just stick
throughout the series once a DF user activates their power it stays activated, the only way to dispel it is either by the user's choice or by the user gets knocked out...
i did consider the fact that distance could've played a role in that case, but why didn't that happen before big mom attacks.
he's even still dragging behind him the scrap metal from the rooftop
i knew one piece has given up on logic a long time ago, but i didn't expect it to reach this level
well, by your logic he should lose grip over his metal arm too
that's not how DF powers work, the user must be knocked out for good to diminish his powers.
now oda decided to retcon the shit out of that rule just to nerf kid
iknow, im just confused why would law say his power got weakened
doflamingo was destroyed but he still kept the bird cage on, kid is supposed to be stronger and he's in better shape yet this shit happens
giving that luffy is fighting equally against kaido, why not kid
besides elemental attacks has proven to have low efficiency, it just comes to show how dumb big mom is because she did the same thing on the rooftop and the sn were fine after that
