Yin-Yang Release: Art of The Hundred Fire Fists is the Fire enhanced version of the Yin-Yang Release: Art Of The Hundred Fists. By imbuing the energy strikes with Fire Release, they are changed into fast, harshly burning fire spears. These spears can get hot enough to burn through rock and the more chakra that is imbued into them before releasing the attack, the hotter the spears become.
