A highly versatile technique whereby the user converts part of their body into wooden branches, which can then be made to grow at astounding speeds and with such force, that they can pierce a person's body with ease. Used predominantly in close-ranged combat, these branches can also be made to exponentially multiply, even when inside a victim. Due to these properties, the technique can be used to fashion short-range weapons akin to a makeshift sword, or else vaulted towards opponents as long-range projectiles, where the branches growth can be triggered remotely by performing the ram seal, skewering the enemy from the inside.
Cutting, also called striking or cloning, is a method of plant propagation. It involves cutting off a piece of a plant, usually the stem or root, which is then put in an appropriate medium. If done properly, the cut piece will grow into a new plant, genetically identical to the plant it was cut from.
Muramasa Otsutsuki can just grow small little points of branches on the back of his hands, and then shoot them out like that. He can still made them grow larger and skewer the enemy. He doesn't need to change a body part into branches to do this.
