Orb of Dimensional Stability
This powerful magic item is found in realms where the forces of the law commonly deal with powerful spellcasters or extraplanar criminals. The orb is a three-inch sphere of green crystal that swirls with an inner light. It projects an invisible field of mystical energy that interferes with any form of extradimensional travel. This is identical to the effects of the spell dimensional anchor, which the exceptions that it affects a 30-foot radius surrounding the orb. In addition, the effect of the orb is continuous; it cannot be shut off. However, the effect can be blocked by a sheet of lead or similar material. Placing the orb in a leadlined box will allow dimensional travel to take place in the area — but the orb itself can never be transported using any of the prohibited spells.
