what if hundreds of mobs are attacking him with the intent to kill, like storm troopers.. will he restrain himself to get hit by each person 3 times, until he can attack back? is he a masochist ??????? in star wars when order 66 is launched he's going to be so screwed.. he can't even ricochet blaster shots back to the attacker because he needs to get shot 3 times and get injured to kill the person, FOR EVERY PERSON..
This is more of a sugestion if want to used, you have already expose that some abilities could be recreated, like to have multiples minds or wills, well this is my sugestion, the abilite or metod to inmortality of the Avatar series, hear me out it's from Lao Ge one of the teachers of Kyoshi, if you don't know Avatar Kyoshi, she manage to live to around 240 years and it's speculate that Lao Ge have around 4000 years, the ability is pure meditation, well it's not full inmortality more like hardcore longevity with youth depending in which point you decide to implemented.
