A useful combo to be used with it can be the impact dial technique, after adding the power of a stored technique, this one's attack power can be raised to great extent, the damage would exceed that of a forbidden technique, hence total destruction xD Also since the technique moves through the body of an opponent and continues onwards then it can affect multiple targets. It would be nice to be used when there is a summon, imagine that my opponent is on the summon, I get beneath it, use this technique, causing the summon to get damaged(or dispersed depending on the summons power) then the attack hits the opponent, he would have no way of knowing that the attack is coming.
Another usage can be, to defend against techniques that are sent towards us, we will also be attacking the opponent simultaneously. Also since it sends shockwaves, it means it's strong against lightning, since it is air/wind that is 'compressed' and given a form, so that makes it effective against earth, wind, lightning, and water, fire would be stronger I believe, or maybe equal, not entirely sure.
Some questions; What is the speed of this technique? Am I right about the elemental strengths and weaknesses? Also after hitting a target and when it continues is power lost? If so how much?
