Infoslave Skull

Use this Stratagem at the end of the Reinforcements step of your opponent's
Movement phase. Select one ADEPTUS
MECHANICUS CORE unit from your army
that is not within Engagement Range of any
enemy units. That unit can shoot as if it were
your Shooting phase, but its models can only
target a single eligible enemy unit that was set
up as Reinforcements this turn and that is
within 12" of their unit when doing so.
