Kinstone Fusion

The art of combining two Kinstones, having them match, and forming one complete, round Kinstone. This "full" Kinstone disappears thereafter. However, good luck comes to both the people who fused the two halves. Kinstones appear in The Minish Cap. In The Minish Cap, Kinstone Fusion is the Equivalent of the Trading Game. Once the Kinstone is fused, many different events may happen depending on who you fused your Kinstone with. Some of these events are, but are not limited to: chests appearing, passage ways that were once blocked by plants are now opened, and bean stalks growing.
