The user manipulates water into the shape of a dragon, which they then direct at a target. The water crashes upon the target, dealing significant physical damage. Ideally, users will use pre-existing bodies of water for this technique, but sufficiently skilled users can instead create the water themselves, spitting the dragon from their mouths. The more talented the user, the greater the amount of water that the dragon can be made from.
