Huh. Why do they copy your native CR, then? Is that not based on how big your coils are?No, sorry. Shadow Clones do not benefit from bloodlines or from ACE. They also aren't penalized by bloodlines, so it's something of a wash. Noburi explains his understanding of why, based on his research results: the Shadow Clone technique creates an entirely artificial chakra system for the shadow clone that isn't actually based on the physical chakra coils of the wielder. It's why his clones don't mimic his own coils, which physically are not 'full size'. He also thinks this explains why the shadow clones weren't affected by the chakra coil-smoothing effect in Orochimaru's cave. When created, they didn't copy the user's smoothed-out coils, and whatever their chakra systems are made of, they didn't respond in the same way as biological chakra systems to the cave water.
... Does this mean Shadow Clones don't copy injuries to the chakra coils? Like, say, Consequences from Noburi's overcharge?
