Knight's Crest

The Knight's Crest is an item in The Legend of Zelda: The Wind Waker. They are worn by Darknuts and are necessary to learn the Hurricane Spin attack.

Location and Uses
Knight's Crests are commonly dropped by Darknuts. They can also be looted from them using the Grappling Hook, but only when they have lost their armor. If you find 10 of them, be sure to bring them to Orca at Outset Island if you want to learn the Hurricane Spin, which will be of great use in the Jalhalla boss fight. They can also be sold to Beedle at Beedle's Shop Ship for 5 Rupees in The Wind Waker and 20 Rupees in The Wind Waker HD. They are kept in the Spoils Bag.

Trivia

 * A single Knight's Crest can be seen on a shelf on Orca's back wall. However, there is no way for you to take it.
 * A great way to farm the Knight's Crests is to visit Ice Ring Isle and "defrost" the Darknut found inside. It respawns indefinitely, so you can get as many as you need for the price of a few Fire Arrows.
