Fractious Echo

A single powerful blow batters the body but leaves the spirit behind and vulnerable to attack. Make a melee Strike that deals bludgeoning damage. If the Strike hits, the target is pushed 10 feet away from you (20 feet on a critical success) and leaves behind a spiritual echo of itself in its original space that lasts for 1 round. The echo is a creature that can take no actions. Anything that targets or would affect the target's echo affects the target and uses the target's statistics. Something that would affect both the target and the echo affects them only once. For example, a fireball spell that included both the target and its echo in the area would require the target attempt only one saving throw and damage the target only once.
