The first one wouldn't be a buff. It'll just be them using extra chakra from strain. For example when ppl use too many med pills, they need to use more chakra each technique due to the drawbacks but those don't work in conjunction with techs that need more chakra. Not sure if I explained that properly looool
Last one. You'd need like full body surges that defend externally also. Like s rank earth armor type things.
S ranks next:
Ototon Genjutsu: Banshī no te de gōmon no seiki) Sound Release Illusionary Art: A Century of Torture at the Hands of a Banshee
Type: Offensive
Rank: S-Rank
Range: Short-Long
Chakra: 40
Damage: N/A
Description: The most powerful sound illusion to be created, A Century of Torture at the Hands of a Banshee is a deviant technique, capable of rendering even the most powerful of enemies riddled with fear. The user will focus his sound chakra into a sound he will produce and which will carry the illusion and trigger it on any enemy that hears it. The illusion triggered is simple but surprisingly effective in all its simplicity: pain. Anyone who hears the sound will feel unimaginable amounts of pain all over their body to such an extent that they may even vomit and lose control of their chakra flow. Upon facing such pain, the enemy will lose control over his body and spasm as they curl to try and alleviate the pain. The longer the target is caught in the illusion the more severe the effect is. The illusion however is just that: an illusion. The pain isn't real or associated with any bodily aspect or damage. The user must, however, sustain the inducing sound and focus into his chakra flow (not being able to mold chakra at the same time) to sustain the effects of the illusion as when the sound ends, the enemy stops feeling the pain and recovers virtually immediately. Sounds that can trigger the illusion and carry it can vary from a whistle (very effective as it can be sustained for a lengthy time and be controlled), scream (less lengthy but easier to perform), music (if the user has a musical instrument), etc. If the sound is momentary, however, it will not induce an effective effect.
Note: usable once every 4 turns
Note: while sustaining the sound, the user cannot attack or move from his position, risking otherwise disturbing the sound he's producing and ending the illusion.
(Ototon: Ōkibo na Hibiki Rendan no Jutsu) - Sound Release: Massive Echo Assault Skill
Rank: S
Type: Offensive
Range: Short-Long
Chakra Cost: 40
Damage Points: 80
Description: This is a much greater and skilled version of the (Ototon: Hibiki Rendan no Jutsu) - Sound Release: Echo Assault Skill technique in which the user gathers his sound chakra into his throat as he inhales afterwards exhaling as he screams, yells or roars. The resulting effect is a massive shockwave of low frequency, high amplitude destructive sound that levels anything in its path. The biggest different is that the user can control the area of affect of the technique, depending on the range he targets and the angle of the sound waves his sound waves take. 180º to 90º, the technique is Short Ranged. 90º to 45º, the technique is Mid-Range and from 5º to 45º the technique is Long Ranged. If used within a water source it receives +20 damage.
Note: Usable once every 3 turns
(Ototon: Ten Ribenji) - Sound Release: Heavenly Revenge
Rank: S
Type: Offensive
Range: Short-Mid
Chakra Cost: 40
Damage: 80
Description: The user stomps his foot on the ground and releases a massive amount of sound chakra, amplifying the "stomp" sound which is released as a wave of low frequency sound through the ground and also through the air, all around. This omni directional sound "explosion" causes the ground to crack open in an omnidirectional area around the user up to mid range and pushes the air all around through massive sound vibrations. These are able to stop any incoming attack (following logic and elemental interactions) but also disable and stop any attack or thing moving or traveling through the ground.
