When the orb is activated, in projects a spherical antimagic field with a diameter of 30 feet emanating from it. Any magical effect that enters the orb's field is suppressed, including raw arcane energy. Summoned creatures and any type of extraplanar entities immediately wink out if they enter the orb's field. If activated when such creatures are in the orb's area of effect, it rolls a caster level check of 1d20+21 against each of those creatures' spell resistance to attempt and make them wink out. The orb's antimagic field also protects those within it against the effects of a mage's disjunction spell. If as a result the orb's field is destroyed, the orb cannot be activated again for 2d12 hours.
