As a free action on your turn, you may spend a Void Point to gain a +2 Void bonus to AC until the beginning of your next turn. You may not spend more than one Void Point in these fashions. Void bonuses always stack. A frightened or panicked character may not spend Void Points. A full night's rest returns your Void Points to maximum, as does an hour's meditation and a Concentration check (DC 15). Unless otherwise specified, any use of Void Points is an extraordinary ability.
