Issen: Flash

While gathering chakra in their sword, the user stands ready to block an opponent's attack while in the Issen Stance. Using great speed and evasion, the user blocks the strike and unleashes the built up chakra in the form of a bright flash of light that spreads for a few meters in all directions. Unlike most Issen Stance techniques, this technique does not damage an opponent. However, anyone within the light that views it will be instantly blinded for a few seconds, opening them to a follow-up attack. Even if the target closes their eyes in time, they will still suffer some disorientation. If more chakra is gathered, the flash can extend further.
