@King Kindred Just as side comment regarding the last post. The chakra of dispelled clones returns to the original user, so she wouldn't have used THAT much chakra. And both the body flicker and chakra coating aren't really high caliber jutsu. Sorry if I'm a bit picky about the details of Jutsu.
Yeah, I read the part about the chakra returning on the wiki, but I don't remember it being said in the actual material.
Edit: Just checked the reference
chapter/pages for it, and I don't know if it's a different translation, but it doesn't say that a dispelled clone's chakra goes back to the user. Just that once the Sage clones from Mount Myoboku are summoned their sage chakra goes into Naruto. But if the chakra goes back to them when they're dispelled I think it's when it's either they're manually dispelled by the user or when the user absorbs their chakra for themselves causing the clone to dispel.
In Rin's case her first clone was destroyed by Akio's clone and Naruto never seemed to regain chakra after his clones were destroyed by someone else.
Sorry. I'm picky about jutsu details as well. Years of Naruto Rp's will do that to a person.
Edit 2: And although chakra coating and body flicker aren't high caliber jutsu doing them multiple times in succession would drain chakra. Plus if the shuriken aren't made specially for absorbing chakra, like Asuma's blade and the White Fang's saber, then it'd cost more chakra than normal to coat them with an element.
