Kinstone

Kinstones are special artifacts made by the Minish which Link can find throughout his quest. Kinstone pieces are fragments of a complete medallion. In order to successfully form a complete Kinstone, two pieces of the same color and with complementary notches must be used.

After completing the first dungeon, Link receives a Kinstone Bag. This allows him to collect and store the pieces he finds or receives. The most common variety of Kinstone piece is green, with blue being slightly rarer and red considerably rare. There are also special gold pieces that are used to make fusions that advance the story. These gold fusions are the only required fusions; the others are completely optional and are not needed to finish the game.

Throughout the game world there are characters holding Kinstone pieces waiting for a matching piece to fuse with. They are identified by thought bubbles appearing above their heads when Link approaches; the symbol in the thought bubble gives an indication of what sort of special event the fusion will result in.

Different kinds of Kinstones for example, fusing Kinstones can reveal a secret passageway in a different area, or make a treasure chest appear. Green Kinstones are, with few exceptions, minor things such as golden enemies and treasure chests due to this color's abundance, while the rarer red and blue Kinstones often produce unique results, such as beanstalks and Pieces of Heart, inspiring characters to perform a certain task or sell a certain item, and so forth
