Their killing intent often extended outwards and becoming physical. Mixing with their will and spiritual strength.

Every warrior's presence takes a different form. Similar to a spirit animals, this force represents what they are. Who they stand for, or simply their true self. Also, presence's vary on size. Depending on control and power. Those who are strong enough, can suppress presence's that rival skyscrapers. While others allow it to run free. Making them incredibly dangerous for allies. But the larger and uncontrolled one's presence, the easier it is to be spotted. Which is its downfall.
