Awaiting his senpai, he was thinking.
Yeah, it has been awhile hasn't it? I used to train with him to learn Earth, now he's teaching me, heh. Neji would proceed to smile slightly remembering the good times they had and how much better they're about to get. Seeing as Jakai would appear, he hears him say for us to get started. Hearing this would get Neji excited and ready for business,
Let's do this!
Taking a stance, Neji would make the hand seals Boar → Ox, then proceeding to place his hands on the ground while channeling his chakra within the ground itself, towards the enemy. Using the chakra that was focused into the ground, he would make the area spiral downwards, causing the floor underneath the opponent to fall.
Advan: The advantage for this would be that you can use from a good distance and cover a lot of ground. This particularly works well in caves or rocky areas since there are so many rocks. It would potentially kill the opponent or cause a lot of terrain that the enemy would have a difficult time getting through, if at all. It's also a quick move, considering you just place chakra into the ground and that's basically it.
Disadvan: The disadvantage to this tech would be that it's only very effective (imo) at a rocky place since most people could avoid this by jumping away or just getting out of the collapsed floor since they're not trapped by all the rocks.
Scenario: A good one I can come up with is that if someone were to use a water tech to create a water source everywhere is to use this, creating a hole and draining that water down the hole so it doesn't come to me.
Focusing his chakra within the soil, Neji begins to concentrate his earth chakra into the ground. Placing his chakra in the ground, he sees that 4 big rock spears start coming out of the ground in multiple direction that would jam into the rocks that were falling from the previous tech.
Advan: A great one would be it comes from multiple directions, making it very hard for the opponent to avoid unless they're going upwards. Depending on how this is placed, it would make it very difficult to actually void and it's versatile.
Disadvan: As you mentioned at the start, if they're able to go up that would basically be the end of the tech. You also have to keep placing chakra into the soil and wait for the spear to completely come out before stopping. That is valuable time that you're wasting and it could potentially end with something bad for you if you're stuck in that situation.
Scenario: One perfect example would be the first tech you introduced. When an opponent is falling from that, you can combo it with this. Since they're falling, they can't necessarily jump up cause they're falling and you can use this to make a spiked pit for them to get impaled to death.
Inhaling, Neji gathers his earth chakra in his mouth. Once at the perfect amount he spits out mud that forms into Neji himself. This stone clone just stands there as Neji prepares to attack it, seeing how durable it actually is. Winding up for a front attack, Neji strikes it and blows off a piece from the earth Neji but it starts to reform and maintain itself back to it's original self,
hmm this is legit.
Advan: A good advantage to this would be that it's a clone. So if you need to inspect anything or you think it's too dangerous you can send this guy out. Also since he's very durable and able to maintain itself despite being hurt, it's a good way to keep the enemy distracted while coming up with another move. This tech can also use up to C ranked moves.
Disadvan: They can only use earth techs instead of multiple ones. Can't really see a disadvantage to his honestly.
Scenario: While fighting against a taijutsu user, I would make this clone to fight him. Since these clones have extra durability, it would be a good fight for him while stalling long enough for me to come up with something better to unleash on him.
It's all good man, I get you're busy lol
