(Doton: Koka no Jutsu) - Earth Release: Hardening Technique
Rank: S
Type: Offense/Defence/Supplementary
Range: Short
Chakra Cost: 40 (-15 per turn)
Damage Points: N/A
Description: The user releases a burst of earth chakra from all over his body. As he does this, a multitude of rock seemingly grows from his skin, forming a large, dense armour or rock much bigger and bulkier than the users original size. The armour can be manipulated and used to create extendable weapons to strike a target with like rudimentary swords or hammers. The downside is that the user cannot mold techniques from other elements a part from earth while sustaining the armor. The armor can be manifested in only specific parts of the body if the user so chooses.
A very useful technique in which the user "grows" rocks from their skin to form a strong armor. While inside the armor, you can manipulate the rocks to form whatever shapes you want, so you can turn your hand into a sword or mace if you so chose. You can also choose to exclude parts of your body if you wanted to, for example leaving your feet unhindered for greater mobility (though you would be top-heavy and unbalanced). This technique, when used to completely cover your body, is also useful for breaking A-rank and below Genjutsu as it's a full-body surge. However, you are slower than normal when using the armor, you're vulnerable to Raiton, you can only use Doton techniques, and it constantly drains your chakra so... There's quite a bit of give-and-take.
(Doton: Dai iwa Kyojin no Jutsu) - Earth Release: Great Stone Golem Technique
Rank: S
Type: Offensive, Supplementary
Range: Short - Long (Made short range of the user with a long range reach)
Chakra cost: 40
Damage points: 80
Description: The user creates a even larger and stronger version of Earth Release: Stone Golem Technique. However, unlike the smaller version, the user creates this stone golem from the ground solely. The user will slam his hand on the ground, manipulating it and shaping it into a large warrior of stone which he can control as long as he keeps his hand in contact with it or with the ground and keeps fueling the technique with chakra. The golem can reach heights of 30 meters and is quite massive but seems to also be capable of moving quite fast as well.
A more powerful version of the A-rank variant, instead of being spat out of the user's mouth, this one can only be "grown" from the ground, making it required to have contact with the ground to use. The user will constantly send chakra towards the golem which in turn controls the golem's movement. You can virtually do anything with the Golem, you can send it towards the opponent as a distraction, or even with force as a projectile based attack. This version is also much larger than the original, being able to shield an entire army squadron on it's own. But even with it's great height, it has just as much speed and movement ability as it's A-rank variant. A draw back includes the golem requires a solid base for movement, also you must remain concentrated towards the golem; you must also be in contact with either the ground or the golem itself to continue controlling it. I think its best to have a clone control it before hand. The golem is not the fastest runner, but it's not slow either, and it has serious strength so it can easily crush enemies with a punch and lift huge, heavy things.
(Doton: Kaido Shōkutsu) - Earth Style: Opening Earth Rising Excavation
Rank: S
Type: Supplementary
Range: Mid-Long
Chakra cost: 40
Damage points: N/A
Description: With the technique, the user can bring up something from deep within the ground by slamming his hands on the ground and manipulating it to forcefully make whatever is contained in it to be expelled upwards. The result of this technique has the appearance of an erupting volcano and can vary in size depending on the users needs.
So a very simple technique, actually very similar to Earth Release: Destructive Rising Rock Pillars. You slam both hands on the ground, and use your Doton chakra to bring up a very large volcano from the earth to push up everything above it. The volcano pushes all of the earth trapped within it, or if you planted things like bombs inside the ground, the bombs (in the manga, it was used to push Zetsu clones up into the air) up high, making the debris that flies out of it look like a volcano erupting. The debris then falls everywhere around the volcano, making everything short-range of the mass of destruction a hazard zone. Clearly, if you can hide some useful items in the ground where you plan to use this technique, it would be best, but if you can't flying rocks is always a good choice. What I really like about this jutsu (I actually just got it now as I looked through it again to write up this summary <.<) is that not only does it attack once when you push things up, but then it attacks a second time with the falling rock debris, forcing your opponent to go as far from the volcano as possible, which generally either puts them long-range from you, or short-range from you, and as mid-range is the general preferred range of NB, you can see how using this with combinations can be helpful.
(Doton: Yama Eikyō) - Earth Release: Mountain Smash
Rank: S
Type: Offensive
Range: Mid-Long
Chakra cost: 70
Damage points: 140
Description: The user will do 3 handseals (Tiger → Ram → Rat) and slam his hands on the ground which creates two enormous rock formations that close in on the opponent from two opposing sides with tremendous force, smashing everything caught in between. Both of these formations are capable of dwarfing even the Demonic Statue of the Outer Path in size. This is one the most strongest Earth based techniques, standing as a testament to both this ability's destructive potential and its difficulty. However, because of its size and power, it can only be used a limited amount of times, requires much chakra and can only be used at least mid range from the user.
Note: Can only be used twice
So, after forming three handseals and slamming your hands on the ground, you can make two very large sections of, well, mountain rise from the ground to crush everything between them. This technique is incredibly powerful and actually overpowers techniques of the same rank due to it's immense chakra cost and damage point value (though it still loses to Forbidden-rank techniques and equal-rank Lightning for being S-rank Earth). Now, while incredibly tall, the mountain is relatively thin (relative to itself). High-speed movement techniques like EIG and Swift should be able to allow the user to run out from between the slabs, but for a normal person I would assume that they would have to destroy the technique as opposed to running from it (if the Demonic Statue of the Outer Path couldn't step out in time, it clearly moves fast enough with a wide enough base to stop normal people from getting out). Overall, this technique is incredibly destructive, but it's main purpose lies in attacking when your opponent doesn't have anywhere to go; using it when your opponent is focused on you and has nothing else to deal with is a bad idea if you're not trying to set them up for a greater combo move.
