The battle capabilities of this technique are far more diverse than that of the other techniques. This is mainly due to fighting being the main purpose of pro-bending. Korra has been seen fighting outside the ring effectively, implementing her pro-bending style waterbending against a variety of opponents. 
Seismic sense is the unique ability to perceive an environment by feeling acute vibrations through the ground. Similar to sonar and echolocation, seismic sense enables the practitioner to detect earthen objects and objects in contact with earth when out of sight. The technique provides a specific map of the user's surroundings, detailed enough so a blind person, such as Toph Beifong, can navigate effortlessly.  It can also be used to detect when someone is lying by feeling their heart and breathing rates through the earth.
Water bullet : The water bullet is a move where a waterbender bends a large amount of water and sends it in a forceful blow toward their target. It is similar to a water jet, but it is more for a quick use since the jet takes more concentration. It is basic yet useful because it takes little time to perform and has a significant effect on the target. Katara used this against Southern Tribe waterbender Hama. 
Without the equilibrium of these two spiritual aspects, waterbenders lose their powers. This was illustrated when Tui's mortal form was killed by Admiral Zhao during the Fire Nation's siege of the Northern Water Tribe. The moon disappeared from the sky, the balance of the world was upset, and the waterbenders defending the North Pole were rendered powerless. 
Ice gauntlet : Similar in technique to the ice claws, a waterbender can freeze water around their hands and turn it into a sharp spike that can be used to scale mountains or impale their opponent. Tonraq made use of this in his battle with Zaheer on Laghima's Peak. 
One noticeable change in the art is a more frequent use of the lower body in bending. Originally, the lower body was not significantly used in waterbending. However, pro-bending has enabled some waterbenders, such as Avatar Korra, to use high arching kicks to direct streams of water.
The symbol for water and waterbending is a circle comprising a stylized rightward-facing ocean wave with three spiral crests breaking over three wavy diagonal lines representing water.  It also shows how the Moon and Ocean Spirits work together, with the moon symbolized by the circular border and the Ocean Spirit symbolized by the picture of an ocean. The symbol is featured in connection with Northern Water Tribe spirituality and on the pendant worn by Katara, originally carved by Master Pakku for her grandmother as an engagement present. 
The technique was invented by Hama during her time as a Fire Nation prisoner following the Southern Water Tribe raids. She came to a realization that living things, animals and humans included, contain large volumes of water, and thus can be bent. Later, the technique was outlawed following the Hundred Year War, with Katara leading the motion for it to be declared illegal. 
Given its extreme nature, only a handful of waterbenders have demonstrated the ability to bloodbend. Due to the complex and sophisticated nature of the technique, it can typically be performed only during a full moon, when a waterbender's power is at its absolute peak. 
Water jet : High pressure jets can be used to force opponents back or even blast clean through a target if focused enough. Water jets are primarily used if the user has the intent of severely hurting their opponents. It was seen being performed by Katara against a pirate.
