Sacred Water

The Sacred Water, originally known as the Water of Life (or Water of life ), is a restorative item which appears in some earlier The Legend of Zelda titles, starting with The Legend of Zelda. It also appears in all three Philips CD-i titles. Its original purpose of restoring Link's health is largely replaced by other potions, instead being given to other characters in later games.

The Legend of Zelda
In The Legend of Zelda, the Water of Life is featured in both blue and red. From the intro, they are respectively known as the Life Potion and 2nd Potion. When used, the Water of Life fully restores Link's health. The Life Potion only has a one-time use while the 2nd Potion can be used twice: when Link first uses the 2nd Potion, it changes back into a Life Potion. If Link has a Life Potion and purchases another, it turns into a 2nd Potion.

Link can only acquire Water of Life from the old women in the various caves, after he obtains the Letter. He can purchase the Life Potion for 40 Rupees and the 2nd Potion for 68 Rupees.

Zelda II: The Adventure of Link
In Zelda II: The Adventure of Link, Link can no longer consume the Water of Life. Instead, its role is as a quest item for town folk. In the Harbor Town of Mido, an old woman wants the Water of Life to cure her daughter's sickness. The Water of Life can be retrieved from a cave in Moruge Swamp that requires the Hammer to enter. If given to the mother, she will allow Link to enter her house and learn the Fairy spell from the town's wise man. In this appearance, it resembles a 2nd Potion.

The Legend of Zelda: Skyward Sword
In The Legend of Zelda: Skyward Sword, Sacred Water is only available at Skyview Spring. The Water Dragon requests Link to obtain another dose of it to heal the wounds inflicted by Ghirahim. Fi registers it as a dowsing target, which cannot be used within Skyview Temple. He must scoop it up in an Empty Bottle and return it to her.

Link: The Faces of Evil / Zelda: The Wand of Gamelon
In Link: The Faces of Evil and Zelda: The Wand of Gamelon, the Water of Life can be obtained by interacting with certain characters. By default, the Water of Life refills all hearts on the spot; however, if the player has a Canteen, some Water of Life will be collected in it for later use. In this appearance, it resembles a Life Potion.

Exclusive to Link: The Faces of Evil are Water of Life bottles hidden within certain levels, usually near the end. When struck, all of Link's hearts are restored, in addition to refilling his Canteen. These bottles never run out of Water of Life.

Zelda's Adventure
In Zelda's Adventure, the Life Potion can be bought from various merchants for 200 Rupees, and is a one-use item that fully restores Zelda's health when consumed. It is represented by a blue phial with a black crown-shaped symbol on it.

Hyrule Warriors Legends
In Hyrule Warriors Legends, the Sacred Water is available to give to a companion fairy in My Fairy mode, increasing her trust.
