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.

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