Unfortunately, it cant be used against human targets, which is a very large letdown. :| Though, it is capable of dispersing jutsu of A rank and below, being an upgraded version of the Clapping Hands Skill jutsu I mentioned. And another thing is, even if it cracks only a little part of a big object, it's enough to cause it to loose it's function/power.
(Ototon: Takanari Kichigai) - Sound Release: Ringing Madness
Rank: A
Type: Supplementary
Range: Short-Mid
Chakra Cost: 30
Damage Points: N/A
Description: The user gathering their chakra into the air having it flow towards the opponent causes this portion of sound to remain in their opponents ears. The ringing continues to grow as time progresses as at first it will disrupt how a person hears eventually hampering their ability to think. From that it starts to mess with their balance until they become incredibly disorientated. Lasts 10 turns and reduces damage of the jutsu used against the user by -5 until this effect wears off.
Basically, you damage their ear drums with this technique. The technique it self continues to disrupt the person his hearing and his ability to think clearly. Lastly, he becomes disorientated, and since each rank has a 20 difference in damage, after 4 turns it lowers the opponent's technique by 1 rank and by 2 ranks after 8 turns. It's also pretty disorienting, imagine a constant humming or buzzing while you try to study. This gives the same effect. It takes away the ability to think clearly after a while (not instantaneous, a few turns, likely 4, increasing in effectiveness as it goes on)
