Specialized Waterbending techniques
Healing
Certain Waterbenders are born with the ability to heal wounds and relieve sickness by redirecting chi paths throughout the body, using water as a catalyst. In the Northern Water Tribe, due to the traditionally patriarchal culture of the tribe, healing is the only aspect of Waterbending taught to female waterbenders, with classes assigned for young girls held in huts towards the development of the ability. In rare cases, a waterbender is shown to naturally have this ability like Katara discovered she had.
Plant Bending
A member of the Foggy Swamp Tribe, Hu, has illustrated that waterbenders can manipulate the vines and roots of plants by bending the ample amount of water within them.
Water Extraction
While travelling Waterbenders carry water skins full of water to bend, a skilled waterbender is able to extract the water from plants for more effective utilization, albeit leaving behind withered, desiccated remains of the former plant life.Waterbenders can also use the water from the air, their sweat or the water underground to waterbend.
Bloodbending
Bloodbending is the ultimate Waterbending technique that allows Waterbenders to bend the water within living creatures, giving a waterbender complete control over it. This can only be done during a Full Moon, when a Waterbender is at his/her full potential. Must be a high level bender and must be approved by 2 or more administrators
Freezing/Evaporation
Waterbenders have the ability to utilize water in its various forms, enabling them to freeze water into ice, immobilizing enemies, and to evaporate it into steam, given them stealth. Skilled waterbenders can freeze water using their breath, as Katara demonstrated in Avatar.
