Well, I obviously know how your weapon works since it's commonly used in movies and whatnot. Besides the twist of it being made of chakra tree wood instead of the usual bamboo, it basically works the same just altered to cater to the ninja world. When charging chakra into the Fugu, you are able to shoot vaccine needle-sized chakra at the opponent which gain substance as a chosen element (or not) and because of their size, are quite hard to see. Upon an elemental hit onto your opponent, the needle serves to spread onto a very small portion around the targeted area of the victim.
Correct!
The quote is self-explanatory.
Good Good.
Self-explanatory but I need help understanding the bold parts, please.
Alright so, there's a difference between Chakra Materialized Needles and Normal Needles. You can pick a normal needle, an actual object/weapon, put it inside the Fugu and shoot it out, at greater speed than normal blowguns. Materialized Needles will always be faster, though, as they cost chakra. The Fugu itself is just a stick that can shoot needles. It can, though, create needles if you put chakra there. These chakra needles are sometimes refered to as Materialized Needles. The turn of materialization is simply the turn where you decided to create the needles and store them on the Fugu. You don't have to shoot the needles right away, you can shoot them at any point in the turn, or at any turn afterwards, as long as you still have needles stored inside the Fugu.
The following are technical restrictions:
1. When you use any of the techniques to create Needles ( Basic Needles, Elemental Needles, Advanced Needles, etc ) you spend chakra and it counts as a move towards the jutsu count.
2. If you choose to shoot them in the same turn, you can shoot how many needles you'd like ( up to a maximum of the number of needles you created ), and they won't cost chakra nor count as a jutsu per turn.
3. If you choose to shoot them in following turns, you will not spend chakra, but it will count as 1 jutsu for the turn. You can shoot how many needles you'd like. You can even shoot a needle, use a jutsu, then shoot another needle. it will only count as 1 jutsu in the turn.
In essence, you only spend chakra when creating needles, not when shooting needles ( safe some exeptions ) and any application of the Fugu will only count as 1 move per turn, regardless of when or how many times you use the applications. ( safe some exceptions )
Self-explanatory but I'll explain if you'd like.
It's cool. It's basic really. You can load 10 needles, you spend 5 chakra per each, each is 10 damage points. Maximum chakra is 50, maximum damage is 100 per usage. Needles are usually shot one by one, even if you do blow them in a fast succession. ( safe some exceptions, like the canon method )
Need you to explain this to me in full, please. z.z
As I explained, in order to store needles into the Fugu you have to either load it manually ( insert paper tags, insert normal needles, etc ) or infuse it which chakra, materializing needles. Each time you do this, there are specific rules for it. Each of these Materializations have a chakra cost attached, as well as a rank, damage points, and a maximum number of needles. The Fugu can only have one kind of needles in it's storage, and the number of needles it can have per kind is described in each of these techniques. Now, as I said before, you always shoot the needles in a succession, be it when you use chakra to shoot them or when you blow through the Fugu. This means 1 by 1, regardless of how fast you actually shoot them.
This Canon Method allows you to dilate the Fugu a bit, and, at once, shoot ALL the stored needles. Instead of dividing the rank and chakra cost of each needle, it's almost like you're shooting one large needle/bullet with the combined power of the method you used to create it. Imagine you have a B rank Fire Materialization, you spend 20 chakra, but you have to create 4 needles. Each needle has only 5 chakra worth, and, thus 10 damage. So each can only stand up to D ranks of weak elements. With Canon, you can simply shoot a B rank bullet, which works against A ranks of the weak element. The ranks of the Bullets is relying on the method you use to create the bullets/load the Fugu, and is fully described here.
For aestethical purposes, the big bullet ripples the element it is composed of around it. Like the sound booms, creating rings around objects moving faster than the speed of sound, it's the same but slower and made of elements.
Explain please. I get the part about the needle seeking out the nearest being with chakra (if the target isn't chosen) at close range with one hand seal.
This is detailed another alternative method of shooting the needles. The Normal method is shooting each one, individually, by blowing through the Fugu. The second alternative method is dilating the fugu and shooting them all at once like a bullet. Third alternative method is without using your mouth:
1. Imagine you are touching the Fugu stick. You can simply point it towards your opponent and it will shoot the needles at your will. No additional chakra cost, no handseal.
2. Imagine you are not touching the Fugu. You make one handseal and spend 15 chakra. This will prompt the fugu to direct itself wherever you want it to go, and shoot as many needles as you'd like.
As I said, any application of the Fugu only spends one 1 move in the jutsu count. You can Materialize Needles and Shoot them Remotely (Without Blowing through the Fugu), however many needles you'd like, and it will not take more than 1 move in the turn. You can't Materialize 2 sets of needles at once: you can't materialize one set, shoot them all, and then materialize another set, and have it count as just 1 jutsu. You may do this, but it will count as another jutsu (and two different sets can't ever cohexist inside the Fugu). So, you can create Fire Needles (basic method), shoot them all, create Venom needles (thieving method), shoot them all and then create Decay Needles (advanced method) and shoot them all. This will count as 3 jutsu (meaning you can't use any other jutsu )
Need you to explain when the 6 stored chakra needles get replaced by the "new set". If they aren't all used by the two turns, does that determine a new set? And can they all be shot with one blow? I understand the elemental effects and chakra cost per needle.
The two turns are just a restriction. You can't create a Fire Needle Set, shoot them all and then create another Fire Set or a Water set, etc. You have to wait 2 turns before you can materialize Basic Needles again. You may shoot all of the needles in the same turn, you may choose to shoot them across the 2 turns, you can choose to shoot them across 5 or 10 turns. You just can't Materialize more needles before the 2 turns pass.
After the two turns, if you still haven't shoot all the needles, you can decide to just keep them, to shoot them another time, or you can delete them, and materialize a different set of needles ( Basic or anything else). Two different Needle sets can't cohexist inside the Fugu, but they can cohexist within the same turn (if you use different methods). This stands for everything else, if you choose another Method, or even the same one, the needles don't stack: The previous needles get erased and new ones appear.
I quite understand this. The Fugu may shoot any physically touched substance in the form of a needle (ex. the example materials stated) but this obviously doesn't mean it absorbs a technique. For example, there is a lingering crystal technique nearby. I touch it with the Fugu for it's sample, it materializes it and it can be shot. Correct? This doesn't last forever but rather for the entirety of a battle/event. And not after the fact. Only able to materialize samples every three turns and all stored needles revert to the sampled substance, element, etc. And after the three turns are up, the needles are restored to chakra needles/needles(?).
All correct, except the last part. You can select a substance (be it other elements, chemicals, biological matter, stuff that is mixed within other stuff, etc), sample it, and the Fugu will create needles of it. After the 3 turns are up, you have the chance to sample a different or the same substance (you don't have to). If you do, the previous needles get erased, and the new ones will appear.
Again, pretty straightforward but instead with basic five, the advance materialization have to do with CE, elemental KKG, etc.
Yeah. If you possess it, you can create needles of it ( Any elements you have (CE, like Decay, Perfume, etc, Advanced Elements like Wood, Scorch, etc, special elements like ink, coral, etc ) and the needles will be the most basic version of the element. if you want somethign more specific, you have to summon the substance, and then the Fugu will automatically create needles for it (no need to sample them ), like, for example, I have Lava, which allows me to create Quicklime. If I don't summon the quicklime, the needles will be simple lava. If I summon the quicklime, the needles can be either lava or quicklime. This also stands for elements/substances your own summons can create, so Venom, Toxins, Oil, Mucus, etc, they can all be made needles without sampling. If there's a basic form of venom, substance, you can just create needles of it, if there are special forms of it, you have to have it on the field.
So, for Raw, no pre-requisite.
For specifics, you have to use a jutsu and create the substance in the field.
Definitely self-explanatory and amazing.
Thank you 
Self-explanatory.
Good good!
Only question about this that I have is that if you use the Fugu as a CQC weapon, the spikes are for that specific purpose at that time, correct? To cause more harm?
Okay, these are the applications that are apart from the Materialization/Shoot jutsu count. If you use them as CQC by either making spikes, growing it past the limits etc, it counts as the CQC jutsu count, and is different. If you choose to shoot a needle and then create spikes and hit someone with it, it counts as 2 jutsu. if you choose to grow it past the limit and create spikes and hit someone with it, they're all just 1 jutsu. CQC vs Shoot, each of the applications that belong to either one count as just 1 jutsu, even if you use multiple of them. At mx, a full usage of the Fugu will only cost 2 jutsu.
For the spikes / non-spikes, yeah, it's for CQC, make it more harmfull.
Explain.
The Fugu is impervious to any S rank, regardless of what the S rank is. But, if you allow it to get hit by an S rank, it gets neutralized for the rest of the battle (you can't use it anymore). It just doesn't destroy it. You can destroy the fugu with a Forbidden jutsu.
Now, that's all passive. Actively, you make spin the Fugu around, and that will create a chakra shield, This chakra shield can protect you against A rank jutsu of any element. If you do use it against A rank, it can defend one jutsu every three turns (thus you defend and then you wait 2 turns to defend again ), if you use it against B rank and lower, it can only defend one jutsu every 2 turns ( thus you defend and then wait 1 turn to defend again.
You try to defend agaisnt 1 S rank, it works poorly (half the damage), but you can never use the Fugu again in the same match. If you try to defend 1 forbidden jutsu, it doesn't work, the fugu gets destroy and you take damage (even if it does weaken it a little bit)
Everything else is just embelishment. You can spin the fugu and you don't have to worry about the jutsu hitting your hands (because there's a chakra shield). If there's a huge boulder being thrown against you, you can block it, but it still has momentum, so you have to deflect it instead of countering it head on ( you don't have the strength to do it ). Deflecting is not only easier, but the technique itself is made specificically to deflect, so any solid should be deflected and any energy can be countered directly, somewhat.
Only need to know the amount of techniques it takes up and why. I understand everything else as explained in some of the previous notes.
Each chakra cost, damage points, amount of needles, etc are stated in the description of eahc method.
