The Power of Intent is formed by the integration of a cultivator's soul, will, mind, and enlightenment towards heaven and earth; peak strong men can even shake heaven and earth with their Battle Intent alone.
For example, War King Elmore Hall's 'Heaven Suppressing' Fist Intent is unrivaled and domineering, integrating into the law itself to strike heavenward, reversing the Great Demon King with the peak strength of a king-level warrior.
Jack Clark's Battle Intent is relatively special, it is the understanding touched upon while slaughtering countless Mutated Beasts under the Blood Moon, when his halberd technique reached its peak amidst the slaughter.
He later mistook it for undefeatable war intent and walked the Road of Invincibility, overpowering peers of the same realm, consolidating an invincible conviction.
