Hero Water

The Hero Water is from Takigakure and it allows a ninja to have at least a ten-fold increase in chakra for a short period of time. Also by drinking drops of the water, a ninja from a village can increase his/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, as Shibuki's father died from the side-effects. 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
