Claws of Truth

The Tukanachi Clan has a special trait, known as the Claws of Truth, that can cause their opponent much stress. However, in order to unlock this special trait, the clan member must have at least killed ten people. The Claws of Truth can activated at any time with no time limit. Once the user makes contact with his opponent using the Claws of Truth, he can not only make the opponent tell nothing but the truth, but he can also look deep into the opponent's secrets. Once he does that, he can make the opponent vulnerable by revealing the secret, causing discontent in the opponent or knowing all the secrets of any move he could not figure out previously, like how to deactivate a jutsu.
