Hero Water

The Hero Water is from Takigakure and it allows a ninja to have a ten-fold (or more) increase in chakra for a short period of time. Also by drinking drops of the water, a ninja from a village can increase his or her fighting ability to compensate for a village's lack of a strong Kage leader. In exchange for this power, the water shortens the user's life span by the number of times his chakra increased. The chakra increase was so potent that, as Suien demonstrated, the user can create a chakra shield to deflect kunai, similar to the Eight Trigrams Palms Heavenly Spin.

The water is produced once every one hundred years from the giant tree that hides the village
