Marble Sphere (Ioun Stone)

Price: 6,500 gp

Weight: -

Slot: None

CL: 12^th

Aura: strong illusion 

Rather than protect the person using it, this stone protects all ioun stones orbiting the character, including the marble sphere ioun stone itself. All affected ioun stones have double the normal hp and hardness, increasing to 20 hp and hardness 10, and are immune to shatter.

In addition, the stones are affected as if by displacement, giving all attempts to strike or grasp them a 50% miss chance. An illusory glamour also switches the color of each stone to a different one, preventing knowledgeable opponents from identifying them.

Prerequisites: Craft Wondrous Item, minor illusion, displacement; Cost to Create: 3,250 gp
