Your character could have a special wavelength that let's her calm down people's souls. You can make it offensive by forcefully removing a person's will to fight by taking the fire out of them. It would also be incredibly effective on madness because it would be purified.[/quote]

I actually came up with something similar to that right after posting earlier.

[quote=@Kouki]As for techniques.

Soul bind: This technique focuses on the chain portion of the sickle, the blade shoots out swerving around in all directions before clasping tight around an object forcefully creating something akin to soul protect and leaving them vulnerable.

Barrier: The chain of your blade fires, stretching and circling around until it forms a barrier around you and your allies, the blade striking the ground and acting for the focal point for you and your meisters soul wavelength that expands and spreads through the chains, defending against the rage of madness and physical attacks.

Soul Resonance
Phantom Blade Dance: By increasing the speed, your blade becomes many, each after-image is an illusion that can slice apart the enemies around you.[/quote]

These are really cool. Thanks for the assist.
