Yokubaribanashi

A forbidden technique which grants power at an advanced rate, but at a heavy price. Limiting (and potentially stopping) the user’s capability to employ Chakra due to claiming one of the user’s arms, At which point the user can only use Chakra through the cursed arm. This happens because the will of the curse curse seeks to wrestle complete control over the user’s sense of peace and morality, wanting to bend the user’s mind to its twisted desires: absorbing any of the user’s Chakra that is tapped into. Feeding the users mind with dark thoughts whenever it does so.

In short, only the user’s cursed arm is capable of using Chakra while the other arm is fully reliant on physical strength alone.

The only way of changing the limitations of the curse is by giving in to evil completely, which is what the curse desires. And with its desires sated, it will no longer seek to work against the user. Allowing the user to use both arms again.

Jutsu History
Jinmu used this forbidden technique in order to learn Chakra Enhanced Strength at a vastly increased rate only to find himself limited to only using his enhanced strength through his deformed and cursed arm: which caused him great shame.

Strengths:
Allows one to gain power and absorb knowledge at a vastly accelerated rate.

Looks kinda cool

Weakness:
Can only be used once by any particular user. (You cannot carry the curse twice.)

Limits the user into only being able to use one arm for anything Chakra related.

Plagues the user's mind unless the user gives into evil.
