Firstly, weapon...
Equipment Name: Tetsumitsuno Arm-Guard
Category: Arm-Guard (Sort of a Gauntlet, actually, but still able to perform jutsus)
Description: Arm-Guard that covers most of the arm, made of Steel, with few spots differing in color made with special Chakra reactive materials exclusive to Tetsumitsuno clan. One can release chakra from them to form chakra claws, with the number of claws depending on the amount of spots, minimum being 3, and usually maximum of 9. The more spots, the harder it gets to maintain the form. A person from Tetsumitsuno clan can also perform some other unique jutsus using the Arm-Guard. In hands of outsider, the Arm-Guard works like a regural one. However, if extensively studied, one could learn to use it, but Tetsumitsuno Clan has developed an affinity towards the Jutsus based on it, and are able to amplify the chakra released from the Arm-Guard.
Then some jutsus based on it.
Jutsu Name: Chakra Release: Chakra Claws
Category: Ninjutsu
Sub-Category: Hiden (Secret) Jutsu (Well, in a way, you need to know how to use the Arm-Guard)
Rank: D-rank to S-rank (The more claws formed, the longer they are, the harder it becomes to sustain the claws. Three claws with minimum lenght is D-Rank, 5 claws with less than average lenght is C-Rank, 7 claws with higher than average length is B-Rank, nine claws with maximum size is A-Rank and so on. Add a rank on each for outsiders.)
Type: Offensive
Range: 0.12-0.4 meters (The size of claws formed. Varies between user.)
Description: The user concentrates to form chakra claws from the spots on the Arm-Guard. These serve as weapons and are as sharp as high-quality weaponn. The more claws the user forms, or the more sharp the claws, the harder it becomes to sustain.
Jutsu Name: Chakra Release: Chakra Blast
Category: Ninjutsu
Sub-Category: Hiden (Secret) Jutsu (See above)
Rank: C-rank
Type: Offensive/Defensive
Range: 3-5 meters
Description: The user concentrates, then shoots a blast of chakra towards target from the spots on the Arm-Guard. The impact sends the opponent flying if within 3 meters, dealing moderate damage, and the attack blocks projectiles within 5 meters in cone of the direction.(If you find it confusing, I can try explaining it some other way =S)
Jutsu Name: Chakra Release: Chakra Shield
Category: Ninjutsu
Sub-Category: Hiden (Secret) Jutsu (See Chakra Claws)
Rank: C-Rank to A-Rank (See description)
Type: Defensive
Range: Arm-Guard (See description)
Description: The user concentrates to form an invisible shield of chakra from the spots on the Arm-Guard. It is as hard as the Arm-Guard, with size depending on the user. The minimum size is 1.5 times the size of the Arm-Guard, usually in a round form, but it's possible to manipulate the shape further with more practice. The maximum size is four times the size of the Arm-Guard. The shield sparkles on impact. The shield constantly uses chakra, especially if shaped differently or with larger cover. While the shield does absorb some elemental jutsus, blocking such attacks drains a lot of chakra, thus limiting the duration the user can sustain the shield.
That's it for now...
