Boil Release: Hiding in the Yellow Springs Technique

By boiling chakra to the highest possible temperature, the user can release a tremendous volume of scalding mist in order to hide their location. Normally, this ability can only be used while in Tailed Beast Mode, however, Ryun Uchiha has shown the ability to use partial transformations in order to replicate this ability or while in his permanent Six Paths Mode.
