Design
The Luck Ring is a silver ring with its outer edge covered in a thick, intricate weave pattern. There are two teardrop-shaped holes in one side of the ring, from which a large, silver charm hangs. This charm is slightly rounded and has similar designs on it to the ring. The most prominent symbol on the charm is the crown symbol on Sora's necklace, which is black and in the center of the charm.

The Lucky Ring's name reflects its use in increasing the "luck" of the wearer and the drop rate of items.
