Water of Life

Water of Life is a consumable item in the Golden Sun series. Like most consumable items, each party member can hold up to 30 Water of Lifes in a single inventory slot. When used, Water of Life revives a downed party member, replenishing their Hit Points to maximum in the process. Water of Life can be bought for 3000 coins and sold for 2250 coins. Also, Water of Life is considered an Artifact, meaning it can be re-purchased if sold or dropped.

Analysis
Although rare, Water of Life can be obtained early in a game, at which point the only other way to revive fallen party members is going to a sanctum. Due to their rarity, however, Water of Life is best saved for boss battles rather than fights with minor enemies. Fortunately, a limitless supply of Water of Life can be obtained from certain minigames or as monster drops, allowing them to be used more freely near the end of a game.

Sooner or later, a party member will learn the Revive Psynergy, which has the same effect as Water of Life for a relatively low cost of only 15 Psynergy Points. While Revive will likely see much more use than Water of Life, players would be wise to keep some Water of Life on hand should all the Adepts who know Revive fall in battle.

While there are Djinn who can revive fallen allies, their success rate is usually low and they rarely restore all of an Adept's Hit Points. While these Djinn do allow for the conservation of Water of Life, they are not the best option when faced with a crisis.
