Name: Spherebender
Type: sphere (you can use the movement of your hands to control it touch-free)
History: This mysterious sphere was discovered around the mine after the meteor incident. The minerals appear to be controllable without touching them. Its origins are unknown.
Effect: It seems to be compatible for combination with other minerals to obtain special effects like elemental attributes. Magic wielders get extra attack bonuses by equipping this.
Look: a fist-sized sphere with a smoothed-rock appearance.
