Absorption Soul Technique

By placing their hand on a target's body this technique allows the user to learn everything that the target knows. Once this is done, the target's soul is ripped from their body, killing them. Because this technique must end with the target's death, Madara Uchiha chose not to use it on Yamato, needing him alive. Nagato used this technique primarily through the Human Path.

Trivia

 * Although the use of this technique usually resulted in the victim's death, the person's soul could also be stored within the Outer Path.
