So far, each realm breakthrough on the martial path unlocked a new ability. The Perfected Warrior realm was no different, unlocking the Amorphous Shadow.
By fusing a warrior's shadow with their Martial Path and Dharma Body, the Amorphous Shadow not only acted as a perfect clone with equal martial abilities as the original but also enabled them to use the Martial Intent—outright destroying anyone with drastically inferior physical attributes. It could also fuse with various body parts to maximize battle prowess.
But while the Martial Intent served as a permanent boost, the Amorphous Shadow only had one life, and once destroyed, couldn't be repaired. For that reason, Perfected Warriors and above typically used their Amorphous Shadow as assassins—rarely letting them out in a frontal confrontation.
