Invisible Blade

Invisible blades are great swordmasters, named after their ability to strike with swords with sudden speed, causing the blade to basically disappear in its movement. Blades of Invisible Blade swordsman seem to teleport from a place to another, as wounds seem to appear from nowhere on the flesh of their targets.

While beginners in this combat art use trickery and deception to mislead their targets and pass through their defenses, advanced users of this style acquire supernatural powers, and become able to literally become invisible until the moment of the inescapable strike comes.
