-the chakra strings burst- O^O hmmmmm you left some wind nature in you strings-forms an ice bow then forms an ice arrow attachs charka strings onto the arrow the shoots it with the bow while the arrow is flying adds wind charka throw the strings as it gets near the a tree i focus all my wind charka into the arrow making it explode-
by the time that arrow gets close to an enemy make sure all the wind chakra in focus in that arrow
the strings are there to make it get to the arrow and help you focus on keeping it in the arrow
