Nice nice, moving on.
Do these 3 handseals, then create a mud flow infront of you, ride it, thus cover the whole field.

Type: Offensive
Range: Mid - Long
Chakra cost: 20

Description: After performing the required 3 set hand seal sequence the user creates and rides a wave of earth that can branch of to attack from a distance. The user can also use the technique to manipulate the terrain and trap the target by wrapping earth round their legs preventing them from moving
As your riding the mud wave, make a handsign, and manipulate the mud thus creating spikes to rise from the mud, impailing the dummy.
(Doton: Retsudo Tenshin) - Earth Release: Mud Needle
Rank: C
Type: Offensive
Range: Short

Description: The user after performing a single hand seal after using earth release: earth flow wave, will create a large needle out of it to impale the opponent.

Once again, you know the deal - Advantage, disadvantage, battle use.
I channel my chakra through my legs spreading it throughout the field as I perform the necessary hand seals, I then manipulate the field making it less solid ans dense and more lenient, thus turning it into mud, I then release a wave of my chakra moving the mud in one direction at the same time causing a somewhat pointy wave to erupt, and with that I finish my first jutsu.
After I've fully created the earth flow wave, I focus my chakra at one exact point at the end of the wave making all the mud racing towards that exact single point, creating a needle shape sharp enough to pierce through objects, and that marks the completion of mud needle.
The advantage the flow wave is that it's a jutsu of a massive scale, making it harder to dodge or counter as it uses a big portion of the terrain, And when using the second jutsu it keeps it's original advantage yet it focuses all the force into a single point making giving further use at piercing.
The disadvantage of both techniques is the speed of them, as the first one requires too many steps from manipulation the ground to making it build up a wave and to finally reach the enemy, and when using the second technique you add yet another process to the chain
Using the first technique as a distraction is definitely a possible use, also it can be used to block an open space the enemy can take advantage of when launching an attack, the second technique can be used to pierce a wall or any object that might stand in my way.
