Surgical Arms OWNER: Nue, Eko RANK: S CLASSIFICATION: Supplementary ELEMENT: - RESTRICTIONS: Sole Med Spec, Medical Training, Nue KKG DESCRIPTION: Made from a sythesized bone like material bonded with Nue cells, the surgical arms are 6 gold colored arms with hands protruding from the user's back. These arms main use is for surgical procedures can be done with one very skilled physician, certain procedures that would normally take more hands can now be done by a single person. Even with this purpose in mind the arms still have use outside of the operating room. The 6 arms function just like the user's normal arms do, giving them extra hands during combat. However due to the purpose of the arms they do very little damage in hand to hand combat, they can however be used to launch or wield weapons. The arms can also be used to form handseals, as due to the Nue cells they are forever a part of the users, but the user can ever only use 1 set of the 6 arms for such a thing with it being difficult to mold any more chakra than that. ABILITIES: Nue Cell Merging[Character SA] Being made of an almost bone like material and bonded with Nue cells the arms once put in are forever a part of the user not being able to remove it. However due to the Nue cells the arms can 'merge' with the user and retract into their body, allowing the Nue to take the arms with them when merging with a patient(or enemy). Due to the cells the user can also heal the arms if cut off or injured. Natural Chakra Pathways [Chakra Reactive] Being made of a synthesized organic material, these prosthetics have the standard chakra pathways that a normal arm would have. Allowing 2 out of the 6 arms to be used in jutsu usage. Fast Reflexes Even though the arms are semi artificial implants, they have great dexterity and reflexes. Medical Ninjutsu Prowess When used for medical ninjutsu either to repair themselves or heal others, the chakra cost of said jutsu is cut in half.

So, the main issue with this item is that it crosses into Oorigami clan territory. We've allowed some instances of additional arms, but the main ones I can think of are Mayonaka (due to spider physiology), puppeteers having additional puppet arms, but they had to actively control them like puppets, and the Hotei religion, which uses spectral hands rather than proper arms.

Aside from that, I believe they'd have to be conductive rather than reactive. Reactive means that chakra is applied, and then a specific effect occurs. Conductive means that you can move the chakra through it as if it were an extension of your body.

I am also concerned that you are attempting to increase handseal speed. The equipment has the fast reflexes SA (which it is already splitting between reflexes and dexterity), but the physical description mentions that the other hands can be used to render handseals; thus, it appears to be an attempt to slip handseal speed, which is made even odder when the pathways skill states that only two arms can use jutsu. How can you use other arms to perform handsigns as part of a jutsu if they are unable to use it?

Medical Ninjutsu Prowess is a definite no. Even if we did allow for such a broad discount (which we do, but only as a clan ability, such as Yamakira receiving a massive doton discount), how does it make sense that these arms would simply reduce the chakra cost of all medical jutsu? It's a ridiculous request.

From what I can gather, I imagine you want two sets of arms that can constantly heal, and two arms that can fight with weapons (mostly because you mentioned they're terrible in melee fights, but you also mentioned weapons can be handled just fine), two that can use ranged attacks or ranged jutsu as needed, and their original two for defense.

The way the item is currently written is either a no or requires extensive editing. The ability to use extra limbs is clan-locked and if it were done via prosthetics, then it'd be puppetry-locked as clarified by the Narashi puppet fanatics clan.

Even if we ignore the above, the most significant flaw is that the arms can perform jutsu with no downsides and that all medical techniques cost half as much.

And if you're going to edit these and somehow come up with a way to make this work, I'd recommend adding a "Coordination" SA to help with balancing. The idea is that the human brain isn't used to controlling that many arms, so it would require extensive training and physical therapy to learn how to do so correctly. Of course, this does not imply that they are all now able to use jutsus and engage in combat at the same time, as this would go too far into Oorigami clan territory.

Note: Another thing I noticed in the first SA you mention: Due to the cells the user can also heal the arms if cut off or injured. Self-repairing abilities are a separate SA of its own with a cost.

And technically as a med-sole, you should not even have an S-rank equipment, that is not medicine or poison. As a sole-non buki spec you are allowed max 1 A and 3 B-ranks.
