Discipline is shaped like an elongated oval. There is a large, teardrop-shaped gap in the middle of the blade. The entire outer edge of Discipline, including the handle, is lined with short, triangular spikes. There is also a longer, thin spike that protrudes from the tip of the blade into the gap in the middle. This model of Ethereal Blade has a yellow glow.
Upon striking targets, the blades create a violet X-shaped slashing effect. At the end of a combo, the effect is larger, and the center is colored pink.
"Discipline" is control obtained by enforcing compliance or order.
Like Judgment, Discipline's attack combos are characterized by broad, swift, spinning attacks. The ground combo consists of a spinning thrust, a 360° swing, another spinning thrust, and a double spin, with the blades extending on the last spin. The finisher has a knockback effect.
The aerial combo consists of an upwards spinning swing, a double spinning slash, and a downward 360° spin slash with knockback.
The ground combo for Discipline+ adds another 360° swing and another thrust before the double-spin finisher.
