Thunder Arts

Thunder Arts are a type of Magic Arts in Kingdom Hearts. It serves as proof that the player is a master in Thunder magic.

To obtain it, you must cast Thunder on a White Mushroom 3 times, when there is a light hovering above it. You will get MP balls, a Synthesis item, and a Thudner Arts.

Obtaining all arts and presenting them to Merlin will give you the Dream Shield. Unlike many other key items, the Thunder Arts can be sold, but at a rather low price.
