Five Elements Seal

Five Element Seal is a technique which produces a powerful seal that is used to block or disturb the flow of chakra in a person.

Usage
Once the seal is completed, the target will become unconscious and unable to fight for a short time. Orochimaru performed this technique to tamper with Naruto Uzumaki's seal. The original seal allowed a small amount of the Nine-Tails' chakra to always mix into Naruto's, but the additional seal disturbs this, preventing Naruto from using the Nine-Tails' chakra or even controlling his own chakra properly. This is because an odd-numbered seal creates an imbalance when placed on top of an even-numbered seal. When Orochimaru later notices that the seal has been removed, he remarks that there are very few ninja capable of doing so, like Jiraiya.
