Psychic Blade

A heretical sorcery of the 'Violet School,' whose scholars sought to transcend the limits of the flesh. 

It condenses pure will to manifest a formless 'Psychic Blade' within one's grasp.
The energy extending from the caster's hand possesses no physical substance, 
yet it is sharper than any steel.

Possessing no physical substance, this blade passes unhindered through steel armor and muscle, cleaving directly into the enemy's mind.
The victim bears no external wounds—not a drop of blood, nor a scratch—yet their soul collapses in agony, torn asunder from within.
