Blue Potion

The Blue Potion, though commonly used to restore both health and magic power, has seen different uses throughout the Zelda franchise. This potion, regardless of game, is the most expensive of the potions, when bought at a Potion Shop, because of its increased replenishment qualities.

Inception and Original Usage
The Blue Potion first appeared in A Link to the Past and is used to restore both Health and Magic. Just like Red Potion and Green Potion, Link needs an empty bottle to carry it in.

In Majora's Mask Link can either purchase a bottle of Blue Potion from the Ikana Canyon Business Scrub for 100 rupees or give a Magic Mushroom to Kotake at the Magic Hags' Potion Shop who will then use it to create Blue Potions and sell them for 60 rupees each. They cure the Curse status Blue Bubbles inflict.

There are two ways to obtain the Blue Potion in The Wind Waker. The first is to collect 4 Boko Baba Seeds from killing Boko Babas and then giving them to Hollo who will mix a blue potion for Link. The second way is to collect 15 Blue Chu Jellys from Blue ChuChus and trade them to Doc Bandam on Windfall Island. He will use them to make a Blue Potion and give Link the first sample for free, and from then on will have it for sale at 60 rupees a bottle. In the whole game, the blue potion is considered the 'ultimate potion' because it can restore Link's magic power and health.

As a Health Restorer Only
Blue Potion in Twilight Princess can be obtained in two ways. The first way is to slay a rare Blue ChuChu, found throughout Hyrule and several dungeons, especially the Lakebed Temple, and scoop up its remains into an empty bottle. The blue remains of a Blue ChuChu act like a red potion, restoring all hearts. The second way is to simply buy the potion itself from the Goron's son in Kakariko Village, the shop in the City in the Sky, or from Malo Mart in Hyrule Castle at a reduced price. In Twilight Princess however, the Blue Potion only restores hearts, as the magic meter was not part of the game. Likewise, the blue potion in The Minish Cap will restore up to 8 Hearts only, considering this game does not incorporate magic either.

Only The Legend of Zelda featured blue potion as red potion's inferior, not in strength, as they were equals. It costs 40 rupees and restores all hearts when used. After the blue potion is used, the slot in the inventory reverts to the Letter.
