Magic Meter

The Magic Meter measures Link's current level of Magic Power and displays how many more magic abilities the young hero is able to cast. It first appeared in the second Legend of Zelda game, The Adventure of Link, appearing later in A Link to the Past, Ocarina of Time, Majora's Mask, and The Wind Waker.

Uses
The Meter appears as a green bar which decreases when Magic Power is expended, although it can be refilled using Magic Jars, drinking special potions, or by being healed by a Great Fairy. Although spells such as the ones in The Adventure of Link and the ones in Ocarina of Time drain magic from the Magic Meter, other items, like the Magic Medallions in A Link to the Past and the Fire, Ice and Light Arrows, also consume magic. The Magic Meter is further used to power various items, such as the Lantern, the Fire and Ice Rod, and the Magic Cape in A Link to the Past.

Magic Meter Upgrades
In most games which use the Magic Meter, it is possible at some point during the game to increase its capacity, which is usually doubled.

Absence in Twilight Princess
Its absence from Twilight Princess has been strongly noted by many, especially given that a green bar appears on beta screens for the game, including screenshots on the back of the game box. It is the only 3D Zelda game without one. It would have been replenished by Green Chu Jelly (see external links).
