Omen of Incursion

Once per battle, at the end of the Reinforcement step of your opponents Movement phase, this model can experience this vision. If it does, select one Grey Knights Core or Grey Knight Character unit from your army that is not within Engagement Range of an enemy units. That unit can shoot as if it were the Shooting phase, but it's models can only target a single eligible unit that was set up as Reinforcements this turn and that is within 12" of their unit when doing so.
