I have been discussing this issue with Osaru for a little while now, while I believe the chakra system is an interesting idea that would've been fun, the staff just don't have the time to go through every jutsu and cost them every time it's created. As of today the chakra system is temporarily suspended. The suspension may become permanent if we don't have too much trouble with people trying to exceed believable limits with their characters.
Have fun everyone, if/when the suspension becomes permanent I will remove all chakra costs, pools, and the chakra system explanation from the site to avoid confusion. Now, you all better get active!
