Water Bending
Water benders can control water in it's three states,liquid,solid,and gas. Water bending techniques is to control the opponent but not to harm them. As like the element air,water is a defensive element. Waterbenders can suspend water from a watersource and slash it at an opponent. They can also create powerful waves and engulf the opponent by droping the wave upon them. Likly if a Waterbender is traveling on land there is no water source to help them defend themselves. As a result waterbenders carry a bottle or skin to contain the water in it. Waterbenders can also collect water from the air and ground. Waterbenders are very noble people just like the Airbenders. They would rather heal then harm.
