What it does
This technique originates from Kirigakure. Using water from the surroundings, the user creates one or more copies of themselves. Unlike the standard Clone Technique, these water clones are physically real, allowing them to interact with others and even perform the same jutsu as the user. Although a single water clone can be quite challenging to a standard genin, In the anime, the clones can alternatively disperse into a mist that act as a smokescreen to briefly cover the area.
Water clones cannot travel too far from their user's location, meaning that running away is a viable option against them. This aside, water clones are useful as support and diversions.
