Why do I have to keep typing this :T_T:*the bones misses the tree completely*
Oh, yeah. We have to work on the accuracy of the bone. xd Okay, usually a bone goes off target when an uneven amount of chakra is spread behind the bone. Like, say, one side has more chakra to it than the other side, than the bone will be pushed over to the side where less chakra was applied when you shoot it out. If the left side of the bone has less chakra pushed behind it than the right side, the bone will end up flying towards the left side and vise versa.
When you shoot the bone off, make sure you have enough chakra powered behind it.
* I concentrate chakra in my bones calcium as I shape it to a sword,than I build more chakra to it to make it thick.Than I make my chakra wrap around it to suppress it,to make the bone thinner and stronger,I also add more chakra to the bone now to make it harder.Now that its small I add another layer of chakra to it than suppress it again to make it leaner.Now as i suppressed it I focus chakra behind the bone to shoot the bone out of my hand,at the same time I also make sure to balance out the chakra in the bone, Now I aim/shoot at the tree quickly replacing it with another bone*
Like that T_T
