Gentle fist being able to temporarily cut off the person your fighting jutsu could also make ppl implant taijutsu to their build so they not spamming jutsu

i think it would be a good idea to make getting different tailed beast a different type of quest for each one for example the 9 tailed fox could be you or the people around you do a raid where have to protect the people of the village bring the to a safe point while also fending off the 9 tailed beast and when the 9 tailed beast dies and all villagers are at the safe point a soul point would spawn where the 9 tailed beast died and you and the people around you would have to complete a trial to obtain the 9 tailed spirit but only the first person to complete the trial gets it and also everyone should have 3 life and the damage of the 9 tailed beast boss should scale on how much people there are with a 10 percent chance for the soul point to spawn
(And also you would be moving the villager npcs from the falling debree and a some of the 9 tailed attacks
