Hammersphere

This sphere is 4 inches in diameter, made of silver, and covered in small rubies. The hammer-and-anvil symbol of Moradin is etched onto its surface in four places.

Once per day, when held aloft and activated, this sphere conjures forth a giant hammer. This hammer functions as a spiritual weapon except that it deals 3d6 points of damage on a successful hit. You do not have to concentrate on the hammer or keep the sphere aloft while it attacks.

Prerequisites: Craft Wondrous Item, greater magic weapon, spiritual weapon.

Cost to Create: 750 gp, 60 XP, 2 days.
