Those with the Mage sight see the bearer of this smooth, black stone pendant as a dark void, an unsettling patch of nothingness in the realm of magic.
Whilst within the Command range of the bearer, all Wizards (friend or foe) suffer a -1 modifier to their Casting and Dispel rolls.
In addition, during the Command sub-phase of their turn, if they are not engaged in combat, this character may attempt to use the Null Stone by making a Leadership test (using their own unmodified Leadership). If this test is passed, until your next Start of Turn sub-phase, this character cannot be targeted by any spells and is immune to the effects of any spells.
