Magic stone

Magic stones (魔石) are magical tools that can amplify magic power and they also serve as multipliers for magic spells.

Description
The magic stones are jewels that come in different shapes and sizes and have different patterns on them. The stones are capable of amplifying the magic power of the one who wields them, and the Elf Tribe are the only ones that can use them to their fullest.

The organization Eye of the Midnight Sun has been collecting these stones and placing them into a sephirot. Julius Novachrono entrusts the Black Bull squad with recovering the stones.

Once the sephirot is complete, Patolli finishes resurrecting the elves. He plans to place the final stone in a pedestal within Clover Castle.
