First; You can use the technique on your hair (hence the ''hari'') but, to make this less confusing, just a needle you shape into your hand, and can expand it up to long range hence the mid-long to not make it so OP that you can expand your hair with the technique, not to mention your hair containing lethal flammable toxic. But, because it's described in the technique hari, I guess it's hair. (Gotta talk with Scorps about this)First NAD technique got approved!
(Katon:Yuudoku Kaen Hari) - Fire Style: Toxic Flame Needle
Type: Attack
Rank: B
Range: Mid-Long
Chakra Cost: 20
Damage Points: 40
Description: The user lights their hari with their chakra.
When the needles tips of the needles contact skin, they burn the opponents skin and inject poison into their body.
Similar to the other fire technique, you gather your fire chakra in your hand and use shape manlipulation on it to create needles of fire that is tipped with poison, if it touches the targets body it will burn right though them.
(Raiton: Sen Tomoshibi) - Lightning Release: Beam of Light
Type: Attack
Rank: S
Range: Mid-Long
Chakra Cost: 40
Damage Points: 80
Description: The user focuses chakra into his/her lungs or mouth.
Then they release their chakra from their mouth to create a large beam of lightning. When the chakra is released, everything in its way will be destroyed, but not humans.
Pretty basic, you gather up a large amount of lighting chakra then you release it via your mouth, that will create a huge beam of lighting that will damage humans but not kill them/destroy them, but everything else that isn't human gets destroyed.
Question: Summoning animals, how does that work for them? They aren't human but.
Second; Clones and Summons, yes. Because they're basically chakra and made out of chakra, and the beam of light can destroy anything if filled with chakra or whatsoever. (Following the elemental weaknesses and strengths of course) So, it can destroy ground, trees, rivers and chakra. So ANYTHING, except for humans. And it's quite the big technique. (Bijuu blast from the Jinchuuriki's? Starts tiny, and expands with the second)
