The user creates a clone that looks exactly like the creator but consists of spilt blood. The clone can attack both with close combat attack and by using techniques. The clones exist in countless numbers like the infinite reflections of two opposing mirrors. Real bodies though they may be they can’t possible possess 100% of the originals strength. Each subsequent reflection in opposing mirrors is weaker than the one before a copy of a copy; No mirror can possess 100% reflectivity. How long they can stand before dissolving back into blood depends on the user's skill and the enemies' strength. And since the clones are created from spilt blood user can form a network of bloody clones that surrounds their enemies and attack them from every side.
