Deku Leaf

The Deku Leaf is an item first introduced in The Wind Waker.

Location
The Deku Leaf is obtained in the Forest Haven from the Great Deku Tree, after the wise Earth Spirit had to interrupt the Korok ceremony because of Makar getting lost in Forbidden Woods. The Leaf is near the top of the Great Deku Tree, so Link must hop from Baba Bud to Baba Bud (and make occasional use of the Grappling Hook) to reach there.

Uses
The Deku Leaf is incredibly useful as an item in two ways. Its first function is that of a makeshift fan. When used on the ground, link fans it very hard, causing a strong puff of wind to blow forward. This air puff can be used to blow apart piles of leaves, stun enemies, and turn pinwheels. However, it cannot go through walls or other objects, and once it hits its target, it stops moving and dissipates instantly. The air puff's usefulness is also detained in the fact that if Link has no magic power, the leaf wilts and cannot be used. The air puff itself, however, does not use any magic power.

The Deku Leaf's more important function is that of a glider. After jumping off of a ledge, using the items results in Link holding the leaf above his head and can glide for long distances, similar to Deku Link's flower propellers. Combined with a Baba Bud launch, the young hero can move vast distances with this item. However, it drains magic power rather quickly, and if Link is outside, he will need the wind to go in his gliding direction to get anywhere. This means that turning in midair while outside is mostly ineffective and eats up most of the magic power. If Link runs out of magic, the leaf wilts once again and is rendered useless until he gets his meter refilled.

Trivia

 * After utilizing the Deku Leaf in midair, continuously tapping the button it is equipped to throughout the flight will reduce the amount of magic that it takes.
