Nenjutsu: Pain Alter

Nenjutsu: Pain Alter is a Nenjutsu technique developed by Meikyou Shisui. By channeling yin chakra into the base of the skull and along the spinal column, the user's perception of pain can be altered.

The most obvious benefit of this technique is that it enables the user to overlook and even outright ignore the debilitating pain of an injury or poison. Alternatively it can be used to counteract the influence of drugs or genjutsu that serve to block or impede the sensations of pain in order to conceal a wound. Pain alter is also a useful skill for medical self-examination; even minor cuts or bruises can become vividly painful, alerting the user to their existence.
