Sound Release: Sound Divinity - The main difference is that you can also utilize a high frequency, to damage/shatter even bones. And that the technique acts internally and not externally. The coating of sound chakra, or I should say, the lack of, can't be used to defend from anything. It is more a matter of infusing the vibrations upon contact. This version also seems more violent in the sense that it shatters completely and doesnt blow back.
Sound Release: Shattering Vibrations~ A very useful technique in the sense that if you are unable to use your lungs, like if under water, you can rely on your chakra and hands to release the attack. Straight forward as you mentioned being a very similar technique to echo assault.
Sound Release: Jackhammer - This technique is pretty useful against users that use hidden like a mole technique I assume? Since their bodies isnt turned into an element and only focusing on turning the ground in to fine sand, youd be able to strike them, correct? And is there a limit on the amount of targets that can be affected, if so, would it weakened? And is it something that can be controlled, in case you have allies on the field?
