(Doton: Doryu Taiga) - Earth Release: Earth Flow River Rank: C Type: Supplementary Range: Short-Mid Chakra Cost: 15 Damage Points: N/A Description: After forming the needed hand seal (Tiger), the user transforms the ground underneath their opponent into a river of mud that throws them off balance and carries them away from the user. The mud created by this technique can also be used as a medium for the Earth Release: Earth Dragon Bullet technique.
With one hand seal you will create a river of mud under the opponent feet. Its throw them off balance as well as the mud carrying the opponent away. From their it becomes difficult for the opponent to stand straight on a moving mud river. You can send attacks while he is down from the mud. The river is made short range of you, and the overall mud length is 5 meters long when created. Right when it is created you can move on to an attack.
(Doton: Ganchuro no Jutsu) - Earth Release: Rock Pillar Prison Technique
Rank: C
Type: Defence/supplementary
Range: Short/Mid
Chakra Cost: 15
Damage Points: N/A
Description: After performing the required hand seals Rat → Horse → Dog → Snake and they then create a large amount of rock pillars to rise from under ground. They can then be controlled to surround their opponent and create a bamboo-like prison of rock.
The user will do 4 hand seals a have rock pillars around the opponent rise from the ground. They are controlled to surround the opponent leaving them trapped. Now the pillars move quick fast when rising, their purpose is simply to trap nothing more. The opponent if caught would take them some time to free themselves before you send an attack. You will have a window of attack. Simple ways if you are stuck in the prison is cutting it with a sword running lightning, or slicing them with wind. Its best cutting them off.
(Doton: Doroku Gaeshi) - Earth Release: Earth Shore Return
Rank: C
Type: Defence
Range: Short
Chakra Cost: 15
Damage Points: N/A
Description: After striking the ground with their hands, the user manipulates the ground in front of him to form a slab that tilts upwards, up to 90º, creating a wall of earth that can defend from incoming frontal attacks. In addition, the user can also create 2 slabs that will rise and tilt to the sides in front of him, as if "opening up" the ground. This can be done to create a clear path if anything hazardous is above the ground in that specific area.
An extremely basic defensive technique. The user will place their hands on the ground rising a large wall upfront of them to block frontal attacks. Note the user can not see through the wall. Its sturdy enough to stop most projectile based techniques. Now as said you can not see through the wall so you can be surprised by attacks from the sides, above or even underground so anticipate an attack from those areas.
(Doton: Doro Hoshi) - Earth Release: Mud Spore
Rank: C
Type: Supplementary
Range: Long
Chakra Cost: 15
Damage Points: N/A
Description: This technique lets the user summon a river of mud infront of them. This technique can have water added to it to speed up the flow and increase its power.
The opponent will create a river up front of them and send it towards the opponent, the river is made of mud and runs slow alone, so its best to add some water to speed it up and have a more impact power. If an opponent is caught they will have restricted movement due to the heaviness of the mud as well as be pushed back. The rver goes up to mid long range. After making the mud you cna go onto another tech making it combo friendly. I would personally heat up the mud and give it a higher attack potency. Its also quick to perform but the river is straightforward and easy to evade.
