Headbands
All the Sages are required a specific headband. This headband has the symbol of their animal companion on it, written in both black paint and the leftover Chakra of the Juubi, as their was not enough to make another Bijuu when The Sage of Six Paths split it up. If this headband is ever broken, the Chakra immediately escapes the headband and enters the body of the Sage, which gives him an extra boost of power and Chakra.
