Chimonamidamonai - Stone HeartEdit

Rank: B

Type: Doton Ninjutsu

This major technique uses chakra to harden the outside of many essential organs in the user’s body. If a death blow occurs by way of piercing the heart or other similar incapacitating strike, it instead does just a nominal amount of damage, leaving the person to die much slower than they would have if they had been struck normally.
