Thunder Arts

The Thunder Arts is an item obtained from White Mushrooms in Kingdom Hearts. It is proof that a White Mushroom acknowledged the player as a master of Thunder magic. In order to obtain it, you must use Thunder magic on a White Mushroom when a light shines above it, three times. If you show it and the other six Arts to Merlin, he will give Goofy the Dream Shield. Its resell value is merely 250 Munny.
