Deku Shield

The Deku Shield is the first Shield usable by Link in.

Overview
The Deku Shield is a simple wooden shield crafted from the bark of the Great Deku Tree. The Kokiri Symbol painted on its surface resembles the Kokiri's Spiritual Stone, the Kokiri's Emerald. Link must first purchase the shield in the Kokiri Shop found in the Kokiri Forest for 40 Rupees to convince Mido that he is worthy of his council with the Great Deku Tree. After passing Mido, Link can purchase another shield from Business Scrubs in either the Lost Woods, Inside the Deku Tree, or within Dodongo's Cavern for 50 Rupees. It is fairly functional, but its durability may be compromised by certain flame attacks, as it instantly burns up if a Fire Keese touches Link or a Dodongo's breath harms him. The Deku Shield can only be equipped while Link is in child form. Although the Hylian Shield is available to child Link, it is far too heavy and it hinders his movement into a sort of "turtle shield" technique. However, the Deku Shield provides a more mobile defense and is well utilized by the Z-Targeting system.

Ocarina of Time Manga
In the, once Link and Mido had lifted the curse of Queen Gohma and relieved her from inside the Great Deku Tree, he requests Link to carve a shield, the Deku Shield, out of his remains once he passes away so it may protect him from evil on his coming journey outside the forest.

Super Smash Bros. Melee
In, Young Link carries the Deku Shield. He can use it to block incoming projectiles while crouching.

Hyrule Warriors
In when using the Spear weapon, Lana is capable of having it transform into various different forest themed weapons, one of them being the Deku Shield. It transforms into the shield while guarding, and appears on her left arm while attacking with the spear in the other during her Focus Spirit Special.
