Mathematical Malignant Annihilate

is the Noble Phantasm of the younger James Moriarty.
It extracts and steals the malevolence of all targets on the field. With the exception of mechanical lifeforms and saints, all creatures have malevolence. Extracting it effectively depowers the target because malevolence includes feelings necessary for combat, such as fighting spirit, hostility, and bloodlust. If you lack those in battle, you're doomed to fall behind.
